Depends if you want function or aesthetics
I love XFCE, but don’t appreciate the author’s attitude to some of his more flawed design decisions, especially when it’s a glaring issue that other DEs approach in a uniform manner that he decides must be done differently.
In my case it was his attitude telling users to go use another DE if they didn’t like how he designed the treatment of a fullscreen application if it lost focus to another monitor, whereupon the panel on the monitor the fullscreen application was running on would overlay the fullscreen application (be it a fullscreen YouTube video, a running game etc).
If that was fixed so that fullscreen applications would be layered above panels despite losing focus then XFCE would be perfect for me.
I currently use Plasma as a result, because I’m a heavy user of my 2nd monitor, and videos & games were getting overlaid by the panel on monitor 1 all the time.
Plasma, Gnome, Win10, Cinnamon, Budgie etc all behave the same way and keep the fullscreen app on top of the panel, so why can’t XFCE? It’s very annoying IMO
