For a couple of weeks Oneiric grows up rapidly... so many people had experienced some newer gtk3 apps on the "shell". But today Unity is... umm.... damned.
I suppose some points:
1. Unity is too slow - yeah that's critical. wasting a lot in almost cases. the evil was compiz? or anything else?
2. Still haven't themerable - OMG... the Unity Panel is really ugly mad!! I think it's better to theming via ccsm or so.
3. Gnome-Shell is fast - yep. to load, switch to overview, gtk3 compatibilities, indicators, almost is better than current Unity especially speed.
4. Number of bugs - Unity has the flood of bugs in there. many cases had been kept remaining from Natty... when finished?
5. Unity-2D didn't follow 3D properly - yes. I really hate Unity-panel. on Oneiric, 2D panel looks ugly on the area of indicators.
So today I'm playing with Gnome-Shell or Pantheon....
I'm afraid that when Unity work on Wayland??? be in time to release 12.04???
Here is my shot on today...
