I like that Orton won. I did not want Cena to win, I'd like Barret to win one day, but totally not yet. At LEAST a year. I'd ask more, but even Sheamus and Lesnar (and probably a few more but those stood out to me as being ridiculously fast) took a year until they got the big one. Giving it to someone who's done nothing, and who might never do anything else (although I think Barret will be great, but who really does know for sure), giving it to them this fast is a huge mistake. Even if you could use the nexus angle. You'd still be giving it to a bunch of rookies.
However, I would have liked, if they had given it to Barrett, for Miz to have cashed in and won. Then, Barrett would enter tomorrow's (todays) Raw, without every actually having held the title, as a "former WWE champion". Possibly create a face Miz, (although this could easily be rectified by him being a dick the next night), and Nexus can use the fact that they have the "talent" to be champions. Also it might have POSSIBLY helped Barrett seem like a Main Eventer. He'd enter the ring with the "former WWE champion...." title, people would start to think he belongs. But again, he'd never have held the belt.
