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 SX730 was launched at a somewhat lower price (by 25 percent) than the G9X, which makes it more attractive for photographers on a tight budget. 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.
Sensor comparison: Canon SX730 vs G9X
The imaging sensor is at the core of digital cameras and its size is one of the main determining factors of image quality. All other things equal, a large sensor will have larger individual pixel-units that offer better low-light sensitivity, wider dynamic range, and richer color-depth than smaller pixels in a sensor of the same technological generation. Further, a large sensor camera will give the photographer additional creative options when using shallow depth-of-field to isolate a subject from its background. On the downside, larger sensors tend to be associated with larger, more expensive camera bodies and lenses.
Of the two cameras under consideration, the Canon SX730 features a 1/2.3-inch sensor and the Canon G9 X an one-inch sensor. The sensor area in the G9X is 314 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 5.6 and 2.7. The sensor in the SX730 has a native 4:3 aspect ratio, while the one in the G9X offers a 3:2 aspect.
Despite having a smaller sensor, the Canon SX730 offers a higher resolution of 20.2 megapixels, compared with 20 MP of the Canon G9 X. This megapixels advantage comes at the cost of a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 1.18μm versus 2.41μm for the G9X). However, it should be noted that the SX730 is a somewhat more recent model (by 1 year and 5 months) than the G9X, and its sensor might have benefitted from technological advances during this time that partly offset its pixel-size disadvantage. Coming back to sensor resolution, it should be mentioned that the SX730 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
The Canon PowerShot SX730 HS has a native sensitivity range from ISO 80 to ISO 3200 The corresponding ISO settings for the Canon PowerShot G9 X are ISO 125 to ISO 12800 (no boost).
For many cameras, data on sensor performance has been reported by DXO Mark. This service assesses and scores the color depth ("DXO Portrait"), dynamic range ("DXO Landscape"), and low-light sensitivity ("DXO Sports") of camera sensors, and also publishes an overall camera score. The following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The G9X has a touchscreen, while the SX730 has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.The SX730 has an articulated LCD that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in snapping selfies. In contrast, the G9X does not have a selfie-screen.
Both the SX730 and the G9X have zoom lenses built in. The SX730 has a 24-960mm f/3.3-6.9 optic and the G9X offers a 28-84mm f/2.0-4.9 (focal lengths in full frame equivalent terms). Hence, the SX730 provides a wider angle of view at the short end, as well as more tele-photo reach at the long end than the G9X. The G9X offers the faster maximum aperture.
Concerning the storage of imaging data, both the SX730 and the G9X write their files to SDXC cards.

- More heavily discounted: Has been on the market for longer (launched in October 2015).
If the count of relative strengths (bullet points above) is taken as a measure, the G9X comes out slightly ahead of the SX730 (11 : 10 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.
In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it remains incomplete and does no justice, for example, to the way the SX730 or the G9X handle or perform in practice. At times, user reviews, such as those published at amazon, address these issues in a useful manner, but such feedback is on many occasions incomplete, inconsistent, and unreliable.

Care should be taken when interpreting the review scores above, though. The assessments were made in relation to similar cameras of the same technological generation. Hence, a score should always be seen in the context of the camera's market launch date and its price, and comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
