The nice part of debian is the possibility to upgrade as soon as a new major release is available without a reinstall in a safe way. My oldest VM was initially installed with debian 5 Lenny back in 2009 is still active currently running debian 12 bookworm.
As for desktop usage I think when you want to play 3D games another distro is better, as debian often uses older versions/kernels which are more stable but less cutting edge.
