MINT?
I hate the new ubuntu interface. Looks like a giant cell phone.
Have you tried x86 Android ?
I don't like neither gnome nor unity,so I use kde (kubuntu). But my system has persistant and very annoying bugs which make me ponder migrating to a different distro altogether, preferably a rolling release kind. But there are advantages to Ubuntu so I don't know yet, perhaps I will stay and just make a new clean install.
Ps I have tried android - on a tablet. I don't understand why you ask this in relevance for desktops. And anyway I would always prefer a truelly open and free OS to Android.
