From what I've seen, mate (the Gnome 2 fork) looks decent too. After the disaster that was Gnome 3 I've went away from full DEs to a simple but great tiling window manager (awesome, that's the name of it as well as the description). Since 99% of my use cases really involve just a terminal or firefox that's probably as good as it gets for me :) No bloat, just great usability without ever needing the mouse - which is especially great on a laptop since touchpads have always been suboptimal pointing devices.
Although I don't use it day to day, I was rather impressed by Cinnamon (on Mint). It's got the GNOME 3 visual wizziness, without all the usability problems that GNOME 3 suffers from.
The Cinnamon desktop is a Kickstarter worthy effort. I believe it supersedes Linux Mint in its possible impact, because it is potentially usable on any Linux flavor.
