Any camera decision will naturally be influenced heavily by the price. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The G7X was launched at a markedly lower price (by 26 percent) than the V-LUX 3, which puts it into a different market segment. Normally, street prices remain initially close to the MSRP, but after a couple of months, the first discounts appear. Later in the product cycle and, in particular, when the replacement model is about to appear, further discounting and stock clearance sales often push the camera price considerably down. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.
The size of the sensor inside a digital camera is one of the key determinants of image quality. A large sensor will tend to have larger individual pixels that provide better low-light sensitivity, wider dynamic range, and richer color-depth than smaller pixel-units in a sensor of the same technological generation. Moreover, a large sensor camera will give the photographer more control over depth-of-field in the image and, thus, the ability to better isolate a subject from the background. On the downside, larger sensors are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.
Of the two cameras under consideration, the Canon G7 X features an one-inch sensor and the Leica V-LUX 3 a 1/2.3-inch sensor. The sensor area in the V-LUX 3 is 76 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.7 and 5.6. The sensor in the G7X has a native 3:2 aspect ratio, while the one in the V-LUX 3 offers a 4:3 aspect.
With 20MP, the G7X offers a higher resolution than the V-LUX 3 (12MP), but the G7X nevertheless has larger individual pixels (pixel pitch of 2.41μm versus 1.53μm for the V-LUX 3) due to its larger sensor. Moreover, the G7X is a much more recent model (by 2 years and 9 months) than the V-LUX 3, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels. Coming back to sensor resolution, it should be mentioned that the V-LUX 3 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
The resolution advantage of the Canon G7 X implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the G7X for good quality output (200 dots per inch) amounts to 27.4 x 18.2 inches or 69.5 x 46.3 cm, for very good quality (250 dpi) 21.9 x 14.6 inches or 55.6 x 37.1 cm, and for excellent quality (300 dpi) 18.2 x 12.2 inches or 46.3 x 30.9 cm. The corresponding values for the Leica V-LUX 3 are 20 x 15 inches or 50.8 x 38.1 cm for good quality, 16 x 12 inches or 40.6 x 30.5 cm for very good quality, and 13.3 x 10 inches or 33.9 x 25.4 cm for excellent quality prints.
The Canon PowerShot G7 X has a native sensitivity range from ISO 125 to ISO 12800. The corresponding ISO settings for the Leica V-LUX 3 are ISO 100 to ISO 3200, with the possibility to increase the ISO range to 100-6400.

Many modern cameras are not only capable of taking still images, but can also record movies. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, and both provide the same movie specifications (1080/60p).
Beyond body and sensor, cameras can and do differ across a range of features. For example, the V-LUX 3 has an electronic viewfinder (202k dots), which can be very helpful when shooting in bright sunlight. In contrast, the G7X relies on live view and the rear LCD for framing. The following table reports on some other key feature differences and similarities of the Canon G7 X, the Leica V-LUX 3, and comparable cameras.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The G7X has a touchscreen, while the V-LUX 3 has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.Both cameras have an articulated rear screen that can be turned to be front-facing. This feature will be particularly appreciated by vloggers and photographers who are interested in taking selfies.
The Canon G7 X has an intervalometer built-in. This enables the photographer to capture time lapse sequences, such as flower blooming, a sunset or moon rise, without purchasing an external camera trigger and related software.
Both the G7X and the V-LUX 3 have zoom lenses built in. The G7X has a 24-100mm f/1.8-2.8 optic and the V-LUX 3 offers a 25-600mm f/2.8-5.2 (focal lengths in full frame equivalent terms). Hence, the Canon provides a wider angle of view at the short end than the Leica, but less tele-photo reach at the long end. The G7X offers the faster maximum aperture.
Concerning the storage of imaging data, both the G7X and the V-LUX 3 write their files to SDXC cards. The G7X supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the V-LUX 3 cannot take advantage of Ultra High Speed SD cards.
For some imaging applications, the extent to which a camera can communicate with its environment can be an important aspect in the camera decision process. The table below provides an overview of the connectivity of the Canon PowerShot G7 X and Leica V-LUX 3 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the G7X offers wifi support, while the V-LUX 3 does not. Wifi can be a very convenient means to transfer image data to an off-camera location.
Both the G7X and the V-LUX 3 have been discontinued, but can regularly be found used on eBay. The V-LUX 3 was replaced by the Leica V-LUX 4, while the G7X was followed by the Canon G7 X Mark II. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Canon and Leica websites.

If the count of individual advantages (bullet points above) is taken as a guide, the G7X is the clear winner of the match-up (18 : 9 points). However, the relevance of individual strengths will vary across photographers, so that you might want to apply your own weighing scheme to the summary points when reflecting and deciding on a new camera. A professional wedding photographer will view the differences between cameras in a way that diverges from the perspective of a travel photog, and a person interested in cityscapes has distinct needs from a macro shooter. Hence, the decision which camera is best and worth buying is often a very personal one.
How about other alternatives? Do the specifications of the Canon G7 X and the Leica V-LUX 3 place the cameras among the top in their class? Find out in the latest Best Travel-Zoom Camera and Best Superzoom Camera listings whether the two cameras rank among the cream of the crop.
In any case, while the specs-based evaluation of cameras can be instructive in revealing their potential as photographic tools, it remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the G7X or the V-LUX 3. User reviews that are available, for instance, at amazon can sometimes shed light on these issues, but such feedback is all too often partial, inconsistent, and inaccurate.
This is where reviews by experts come in. The adjacent summary-table relays the overall verdicts of several of the most popular camera review sites (amateurphotographer [AP], cameralabs [CL], dpreview [DPR], ephotozine [EPZ], photographyblog [PB]). As can be seen, the professional reviewers agree in many cases on the quality of different cameras, but sometimes their assessments diverge, reinforcing the earlier point that a camera decision is often a very personal choice.

Care should be taken when interpreting the review scores above, though. The ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
