The 'All Canon EF-M lenses' club

I own both standard zoom kit lenses and did a comparison test to find out which one to sell, but decided to keep them both because is worth more to keep them as they complement each other on their pros and cons than their resale value.
From my copies, the 15-45 is better at shorter focal lengths while the 18-55 is better at the longer range. 18-55 has a better built but 15-45 is light and portable which is good but it feels like wouldn't last.

I've found most of the Canon native EF-M lens while sharp, are compromised by heavy vignetting which normally doesn't get the attention it deserves. This is by design since Canon wanted to keep these lenses small. I don't own the complete collection but this is easy to find out in many reviews, it is just physics.
Probably the only exception being the 32mm but its bokeh is not that pretty IMHO.
I really like the 22 for its size and focal length versatility but always wished Canon had a premium version with less vignetting and faster AF speed.
The lens I use when performance and image quality matter more than convenience or portability is the Canon EF 35mm F2 IS. I bought that over the EF-M 32mm because of being future proof, no vignetting and work with the speed booster as a 28mm f1.4 lens, but again is not as portable as the EF-M 32mm.
My 11-22 gets the work done, but is average in sharpness. The colors that come from it are meh, probably has something to do with the coatings or is just me.
I also have the EF 40mm which is good for the price and very compact but an average lens.
For Tele I use the value oriented EF-S 55-250 which I'm happy with, only need to add a good teleconverter or will succumb to the Sigma 150-600
Right now, I'm sitting on the fence between staying with the M long term or moving on to the R APS-C R10, but not excited to further commit to Canon nor have a good impression about Fuji or Sony.
