Most customizable

[Elvish Legion]

XFCE Gnome or KDE which is more customizable? I really like gnome and xfce but am willing to give KDE a try

They're all the most customizable, depending on whom you ask. This question will just end up in an endless "my desktop environment is better than your desktop environment debate."

If you want support, you should explain what you want to customize.
