The main issue you will have with mint, is that it is in fact ubuntu with some extras (cinnamon, etc). It uses the ubuntu repositories directly.
If it's just the unity shell you dislike, then yes mint will be one way of solving that, but you just as easily install a different desktop. Personally of the DEs I prefer XFCE or KDE to gnome-shell and mate (gnome 2 fork), but YMMV.
