I’m using Debian 12 stable and I do everything on it, even gaming. I use flatpaks to keep certain apps that benefit from being up to date, and I install backported kernel and mesa when they release for more performance (amd gpu).
I’ve been on and off with vanilla Debian for years while distrohopping, but I tried out Debian 11 testing and everything just worked for me, am still using that same install but I’m sticking to stable branch now.
Also, proprietary drivers are now officially supported by Debian as of Debian 12, and are available to install out of the box without needing to search for them or add the non-free repositories now, which was a pretty big roadblock for a lot of people.
