Body comparison: Canon 20D vs M6
An illustration of the physical size and weight of the Canon 20D and the Canon M6 is provided in the side-by-side display below. The two cameras are presented according to their relative size. Three consecutive perspectives from the front, the top, and the back are available. All width, height and depth measures are rounded to the nearest millimeter.
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Canon M6 is considerably smaller (50 percent) than the Canon 20D. Moreover, the M6 is substantially lighter (49 percent) than the 20D. In this context, it is worth noting that neither the 20D nor the M6 are weather-sealed.
The above size and weight comparisons are to some extent incomplete since they do not consider the interchangeable lenses that both of these cameras require. Hence, you might want to study and compare the specifications of available lenses in order to get the full picture of the size and weight of the two camera systems.

Any camera decision will naturally be influenced heavily by the price. The retail prices at the time of the camera’s release place the model in the market relative to other models in the producer’s line-up and the competition. The M6 was launched at a markedly lower price (by 48 percent) than the 20D, 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.
Sensor comparison: Canon 20D vs M6
The imaging sensor is at the core of digital cameras and its size is one of the main determining factors of image quality. A large sensor will generally have larger individual pixels that offer better low-light sensitivity, provide wider dynamic range, and have richer color-depth than smaller pixels 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 tend to be associated with larger, more expensive camera bodies and lenses.
Both cameras under consideration feature an APS-C sensor, but their sensors differ slightly in size. The sensor area in the M6 is 2 percent smaller. They nevertheless have the same format factor of 1.6. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.
Technology-wise, the M6 uses a more advanced image processing engine (DIGIC 7) than the 20D (DIGIC 2), with benefits for noise reduction, color accuracy, and processing speed.
Despite having a slightly smaller sensor, the M6 offers a higher resolution of 24 megapixels, compared with 8.2 MP of the 20D. 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 3.72μm versus 6.42μm for the 20D). However, it should be noted that the M6 is much more recent (by 12 years and 6 months) than the 20D, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently.
The M6 has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during video recording.
The Canon EOS 20D has a native sensitivity range from ISO 100 to ISO 1600, which can be extended to ISO 100-3200. The corresponding ISO settings for the Canon EOS M6 are ISO 100 to ISO 25600 (no boost).
For many cameras, data on sensor performance has been reported by DXO Mark. This service determines an overall sensor rating, as well as sub-scores for low-light sensitivity ("DXO Sports"), dynamic range ("DXO Landscape"), and color depth ("DXO Portrait"). The following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.

Many modern cameras are not only capable of taking still images, but can also record movies. The M6 indeed provides for movie recording, while the 20D does not. The highest resolution format that the M6 can use is 1080/60p.
Feature comparison: Canon 20D vs M6
Apart from body and sensor, cameras can and do differ across a range of features. For example, the 20D has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the M6 relies on live view and the rear LCD for framing. That said, the M6 can be equipped with an optional viewfinder – the EVF-DC2. The following table reports on some other key feature differences and similarities of the Canon 20D, the Canon M6, and comparable cameras.

One feature that is present on the 20D, but is missing on the M6 is a top-level LCD. While being, of course, smaller than the rear screen, the control panel conveys some of the essential shooting information and can be convenient for quick and easy settings verification.The M6 has an articulated screen that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in taking selfies. In contrast, the 20D does not have a selfie-screen.
The 20D writes its imaging data to Compact Flash cards, while the M6 uses SDXC cards.
Connectivity comparison: Canon 20D vs M6
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 EOS 20D and Canon EOS M6 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the M6 offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the 20D does not offer wifi capability.
Studio photographers will appreciate that the Canon 20D (unlike the M6) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.
The M6 is a recent model that features in the current product line-up of Canon. In contrast, the 20D has been discontinued (but it can be found pre-owned on eBay). As a replacement in the same line of cameras, the 20D was succeeded by the Canon 30D.
Review summary: Canon 20D vs M6
So what is the bottom line? Is the Canon 20D better than the Canon M6 or vice versa? A synthesis of the relative strong points of each of the models is listed below.

If the number of relative strengths (bullet points above) is taken as a guide, the M6 is the clear winner of the contest (19 : 6 points). However, the pertinence of the various camera strengths will differ across photographers, so that you might want to weigh individual camera traits according to their importance for your own imaging needs before making a camera decision.
In any case, while the comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it remains partial and cannot reveal, for example, the handling experience and imaging performance when actually working with the 20D or the M6. 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.

The review scores listed above should be treated with care, though. The ratings are only valid when referring to cameras in the same category and of the same age. Hence, a score should always be seen in the context of the camera's market launch date and its price, and comparisons of ratings among very different cameras or across long time periods have little meaning. Also, please note that some of the review sites have changed their methodology and reporting over time.
