My favourite DE has got to be Cinnamon, as much as I like KDE and XFCE, I prefer the simplicity of cinnamon where as in KDE has a bit too much of everything in the customization scene and XFCE I find a little tricky to get tiling working right.
Cinnamon to me is perfect as I easily transferred from Win 10 to Mint and soon Manjaro Cinnamon Edition.
What is your favourite DE and why? Tiling WM DE’s can be counted as well seeing as they have nifty navigation features.
GNOME. Won’t say I don’t hate it sometimes but every time after a few weeks using anything else I’m back to gnome. The polish and smoothness are unparalleled, and I don’t really customize a lot. I did used the Plasma 6 beta and seemed great even if it’s not my preference of design language, but haven’t tried since. I should give it another go.
