I've been using Fedora for the past few months and Pop OS for some months before that.

Debian was my first choice after Pop because of ideological reasons - non corporate structure mainly. But I couldn't get games to work properly (my PC is only 7-8 months old). So I've been trying Fedora, but the more I learn about Red Hat and it's involvement, it's harder to stick to the distro.

What would be a good way to setup Debian (and KDE, because apparently GNOME is also Red Hat's, although I do like the environment) so that it works well for my use case? The two year old DE and app versions does bother me but I guess I can learn to live with it. Do I try testing? Do I use backports?
