I use it on two desktops and a lap-top, all running long-term Mint Maya (I see no benefit so far in updating to newer, short-term versions - I see Olivia being touted this week).
I dropped Ubuntu when it came time to move from 10.04 to 12.x - far too much hassle, couldn't understand unity, too much overhead. I switched to Mint Maya + Mate and have very few quibbles with it. The impetus to use Mint came from this forum! :)
Main quibbles include klipper, which is not as good as windows' clipmate but is just about adequate, and kalarm. The latter is causing some annoyance. On Ubuntu 10.04 it ran autonomously; now it requires akonadi server which is heavy and unnecessary for a single app (I do not otherwise use PIM). So far I've been unable to find a good replacement.
I've seen several alternative desktops mentioned for Mint, including KDE, which I have only minimal need of. When I first switched, Cinnamon was noted by Mint as possibly having bugs, being a new interface, so I opted for Mate. I don't think xfce was available at that point, or it was hidden, or something.
I found I was using a lot of panel/task-bar space (I typically have 15-20 apps open) so I added an extra bar to the top of the screen and moved all the icons such as klipper, sound, date etc to that. Between them, those icons take up about half the bar!
