I enjoy playing around with stuff on my computer, trying out this and that. Which is why I love Linux Mint. So many things to try, Lots of options, and all easy to use. If I break it while messing with it, I don't care. It's easy to start all over again.
That said, I tend to mostly use the Gnome environment to play around in. I like to try KDE every once in a while, for two reasons. Lots of eye candy, and it's the only DE that gives me total individual control over the two desktops I use. However, there are other issues with KDE that tend to spoil my experience, and I end up back with Gnome.
Currently though, I started using Cinnamon. I like that it offers an experience like that of Gnome 2, though the application menu provided with it is a bit too spastic for me. By that, I mean having to move my mouse from the category to the selections, often results in a sudden jump to an adjacent category, as my ability to precisely track the mouse in a straight line isn't as it should be.
But I'm still trying and tinkering. Things can only get better.
As for my votes, I selected both Cinnamon and KDE.
