KDE sets a really high bar with all the packages and extensibility. Almost everything (not including the lesser known and used packages) is feature-packed and just works. I really don’t know any other software that constantly amazes me like KDE.

Vanilla Gnome. It’s simple/boring, and I like that. It seems like most people that like Gnome don’t care that it’s not a poweruser DE, and aren’t excited to talk about it either.

GNOME, for sure. It works out of the box, and it’s kind of pretty out of the box.

I also tried it on a touch screen PX and it works surprisingly well.

I usually use WindowMaker or FVWM but as a desktop environment… CDE
