I tried Mint with Cinnamon a few months ago. I normally use Gnome classic with XMonad as the window manager. Some things that are in Gnome were missing in Cinnamon (bluetooth settings was an example IIRC, but I don't remember the details), and I ended up with a mess of Gnome and Cinnamon, having some apps installed twice (the Cinnamon version and the Gnome version). Other things required some manual work, like integrating Dropbox with Nemo. I ended up going back to Ubuntu.
