There always is a huge room for subjectivity, edge cases and other critique in this. But generally saying I'd say yes. My experience mostly is about desktop/laptop (non-gaming, on-board video only) though.
Same. The Ubuntu long term support releases are quite conservative.
I did find the Unity interface more polished however.
It seemed like Canonical did a lot of UX research, to make things like the "power off" button adjoin the corner of the screen, so you could imprecisely flick the cursor and know it has hit the target. It also worked a lot better under old hardware.
I still use Unity with community support. It's a shame, I think as I remembered seeing the Unity interface at work sometimes and thinking that Ubuntu was making inroads.
