I was quite satisfied with Debian Stable for a few years on at least two different laptops, and felt I had found my "forever distro", until I got a Framework laptop whose AMD graphics were quite buggy on it. In order to get rid of all the issues, I had to upgrade to Testing and install a mainline Liquorix kernel (and along the way, I briefly made a Frankendebian and fiddled with kernel parameters). While my years of experience with Debian and derivatives has prevented me from breaking anything, I do wish I didn't have to use all of this beta-quality software just to prevent games from freezing and crashing constantly, just because I bought "new" (about a year old) hardware.

I still want to keep Debian, because I've found nothing else that works quite as elegantly or stably, but I'm hoping to find ways to get the performance I need without Liquorix, and if something forces me to reinstall between now and the time Debian Trixie becomes stable, I'll probably give Fedora or KDE Neon another try.
