To be honest: I can't see any point in such comparisons.
I might be convinced of a change of mind if I saw any excellent, artistic, time-enduring (for generations) photographic masterworks - in the photos taken, of course - which prove that the amount of (additional) money spent makes the difference. In the last ten years I haven't come across any photo that shows that the Leica or any other high-priced camera makes the difference. It still is the person behind the lens and body.
In the last century there were photographers who proved exactly this ... and were lucky to have the best tool for it, a Leica. But it's the genius of the photographers and their special way of showing us what they saw in the way they saw it which makes the difference. The Leica was just the tool to reach that aim in the best possible way at the time.
There are many superb shots in the mu-43 threads with cheaper ad mid-price cameras ... and there are quite a lot of average shots taken with highest-price gear as well. To me it's the outcome that counts, and that is the perfect photo (able to really touch peoples' hearts).
While I agree with the sentiment of your statement, I can't honestly see the point of you lecturing on the need for photographic talent trumping the need for good gear. Part of the fun of having gear for some of us is to test and compare it. I'm an engineer, this sort of analysis is just part of how my brain works.
Of course a Leica doesn't make you a better photographer. I don't expect the camera to magically transform me into Cartier-Bresson, Constantine Manos, or any of the other brilliant street photographers that shoot Leica. I chose Leica for my full size body because I like the idea of shooting manual, a concept that MFT bodies don't promote with all of the tech that gets in the way, at least for me. I love having my GM1 for carrying while cycling or when I need some really crazy reach, and I have no intention of getting rid of it.
The ultimate goal of this comparison is to provide entertainment and an honest look at what a Leica body gives you in terms of IQ, since we often talk about FF vs MFT and Leica FF is probably the closest to MFT in terms of Dynamic Range and ISO performance.
Even looking in the shootout page at all is a waste of time with the attitude of wanting to show that it's the glass or body that makes any difference. Any good photographer can make great images with any camera and any lens. That's not the point. The point is to have fun and see how things are similar and how they're different.
