I’ve tried a lot of Linux desktop environments, and Mint is easily my favorite. I can’t quite explain why except that it’s the only one I started using and never wanted to move away from or try another. Mate is probably a close second.
I’ve been a Cinnamon user for a long time and before that I was using MATE. I’m currently on GNOME but to tell you the truth I’m not satisfied. Cinnamon’s great.
