With the lens selection you already have, you’re a perfect candidate for R (just as you were for M). R is already excellent. I mean really really excellent.
R2
I know I would be, but the M6ii checked off so many boxes for me that I don't see in any R options yet. Very compact (with compact lenses), 3 dials to control aperture, ss, and ISO independently, affordable lenses, tilitng screen instead of flip out, and it has some features you only see on Canon's more expensive cameras like custom modes and an always available e-shutter.
I'm in the same place you are. The R50 looks like a fantastic upgrade to the M50ii at a very attractive price point... the AF looks so good that I"m tempted to go for it plus the RF-S 18-150 and sell off an M200 and my EF-M 18-150 (keeping my M6ii's and all the 'wider' M primes and zooms).
When I think deeply about why I would do that... it would be to get the better AF with long lenses (Siggy 100-600 C, EF-S 5-250 IS STM and better downsampled 4k video. Upgrade cost probably around $300 - $400 with the mentioned sell-offs.
When I think MORE deeply about the consequences of that R50 upgrade... I realize I would lose reach for the telephoto shots (24 MP vs 32 MP for my M6ii's), and the video isn't all that much of an upgrade from the M6ii, really... the more logical upgrade for me would be the R7 with the much better IBIS and CLOG3 video...
But for the R7 + RF-S 18-150 we're now talking a $1000 upgrade cost, even if I 'replace' one of my M6ii's and the EF-M 18-150, which I've already decided is too much money - plus the R7 doesn't have that 'tiny' M form factor and the tilting finder and removable EVF I like so much.
Which leaves me keeping exactly what I've got with the 'very good' M system! But liking those R APSC feature upgrades, which continue to pull ahead of the M bodies. Canon will likely eventually pull me into the R system, as they seem to be doing a great job with their RF-S body lineup (but way too slow giving us more RF-S APS-C lenses), but now isn't the time.
Canon knows exactly what it's doing with their R body feature/price/performance tiers, dang it!! Dangling that apple...
But with M all but dead I hate the idea that I need to build up my collection of lenses now or risk not being able to find the lens I want in 2 or 3 years.
