I too will be happy with any of the three winning this season (Roy if only because it means that I will have predicted the winner from the get go). Even then, I don't think it will be Roy, but if he does produce the best work of the three in the finals he will have earned it. What is nice is all three have had really good looks and really weak looks, so there is no real stand out who SHOULD win but we get disappointed when a less par designer wins.
In Laura's and Tate's seasons I felt they were denied the win. Roy of course was in the same season as Laura and even there I felt he'd been in the final three if he hadn't done the wig disaster (he had by far the better sculpt and paint job of the bottom two IMHO). So no, he wasn't denied that chance - he blew it, but learned I think because this was better than his previous final four makeup.
But what I like most of all - they all were humble about making it to the finals - either again, or for the first time (Roy's reaction to making the finals is the most precious one I've ever seen on this show - though second I think to Justin's in "PR" if by a hair). No one felt entitled (and if they did - their skills backed up the bravado), and all I feel will be genuinely happy for whomever wins even if they are disappointed in the
