I think that's a fairly debateable claim. It's the best right now seeing as it's the only 1 with ICS. If the hardware doesn't impress your friend with the RAZR or Rezound, it wouldn't with the Nexus, either. It's all ICS.
No. The other two aren't as responsive for one. And also the screen is great on this. Its a combination of everything that I want.
The only complaint I have is the battery takes a long time to charge
