You know, I thought Pine was a great Kirk. Really captured the sort of brashness that Shat gave Kirk.
Sorry, couldn't resist.
Seriously though, yeah I don't think they could've cast any one better than Quinto, he was so Spock! For me, of all the new actors, Quinto was the one that seemed the most like his part, with Urbane as a close second.
