Debian is the most stable operating system ever, and it’s new version 12, is a really good OS.
What I liked was that it starts quick, never crashes, uses minimal system resources, and with GNOME has an excellent UI. Being a Linux OS that isn’t Ubuntu and isn’t Windows, it doesn’t spy on me.
Also love operating systems that use Bash or similar. I know how to drive them, I don’t know how to drive MSDOS.
I have a very powerful computer but the start time difference between Windows 11 and Debian is insane. Debian starts almost instantly.
I was specifically trying Debian as a gaming platform, so I installed Steam and GOG and a couple of Windows games running through proton. They worked really well.
In the end I had to go back to Window, because it’s just not there for me yet. Most games worked well, but a few have unacceptably low performance. It requires a bit of fiddling to get everything working right as well, because some of the defaults prevent people from just gaming.
