My big surprise in this thread is that there are so many different views on what makes a "real" Leica.
For what it's worth, I'm pretty agnostic when it comes to VF. If the EVF refreshes quickly enough that I can snag a split-second expression, then it's good enough for me. I'm in my early 30s and I grew up looking at screens, so an EVF doesn't bother me. Besides, if I want a magical viewfinder experience, I'll just break out my Rollei! Nothing like it.
As for the FOV issue with APS-C sensors, I'm mostly a 50mm+ kind of guy, and rarely need something wider. Have been using an X100F for about a year, and most of the reason I started looking for a new camera was because the 35mm equiv lens on that camera feels too wide for the way I see.
I am also coming at this decision from an unusual position, at least for this forum: I currently own no M-mount lenses.
