For those who want something close to Debian testing, #siduction (by default #KDE #Plasma6) might be worth a try. It is unstable (Codename: Sid), thus before testing. This means it is tested but, it is certainly not as stable as testing.
But here is the twist. Use it with #btrfs or #timeshift and #ext4 to have efficient tools for a rollback once it breaks (and it will break sporadically) and you should be good.
