With Ubuntu which one you like most( hope many had tried Gnome 3 as well)? I played with all and I like Gnome 3 the most. To me it looks most elegant though gnome 2 is easier to use.
unity is little buggy on live cd after solving some i didnt have any problem i like it more than gnome 3 but as per my default distro hard for me to say i can trust unity alone like to ok its cool fast eyecandy but i wait i am pretty happy with my ubuntu 10.10 so i stick with it for few more months maybe then
Of the choices I chose Gnome 2, but I'm actually using Xfce (Xubuntu) on my main computer and have Lxde (lubuntu) on my other, really old computer.
