I use a X11 due to my gpu a 1660 ti and my drivers which I need for gaming. Wayland only worked for me when I did not have nvidia drivers installed, so I had to move back to X11 after I installed my drivers, but for the short time I used wayland it was sufficient enough for my daily tasks when I was not gaming. I will be sticking with X11 until Wayland is stable enough for my nvidia gpu or when I buy a new pc and get a amd gpu.
I have been using Debian 11 as a my daily driver for the past couple years, sure it may be old and outdated and doesn’t get as great of performance on games due to the old kernel, but I would rather have stability than the newest software. Everything I need works great. I will soon upgrade to Debian 12!
I use Debian 12 on my main pc, and on my laptop I use a OS that is based on Debian
