X11 is deprecated, it's been removed from RHEL, and hasn't had dedicated maintainers for years. You might as well switch to Wayland (and xwayland if needed) now, it's not really the case that you have an option.
Still no issues on Debian.
I imagine you're talking about stability issues and not the numerous security flaws with X11 that are baked in to the protocol. Wayland is an improvement for many reasons, not just stability and the fact that it is actively developed unlike X11.
Some reading:
Oh, I've followed this stuff for years and years. I've been using Linux pretty much exclusively for a quarter of a century. People love to harp on the security issues, but from what I've seen that's pretty much theoretical. The only real compelling argument is that developers are leaning toward Wayland, so that's the way it will go. I'm sure some day I'll go to update and it'll be time to make that change.
I'm not a developer. I wasn't super happy with the change to systemd, but it's not like I was the one that had to deal with the init v issues, so when it changed, I went along. I'm sure the same will happen with Wayland. The last time I tried it, a lot of my decades of cruft didn't work, shortcuts and workflow issues. Sure, I should probably clean up all that crap anyway, but like I said, it'll happen when it happens. Until then, I'm completely happy with X11.
Little late to the party, but I'll chime in. I have a 3080, and for the most part, Wayland works, but there are a few problems that keep me from using it as a daily driver. G-Sync doesn't work at all, and when I put my PC to sleep, upon wake I end up needing to do a full reboot because of severe graphical issues. When it is running though, it's pretty smooth, with only a few graphical issues here and there. I still daily drive X11 though until the major bugs are fixed.

From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.
