I dare anyone to say that Grey Knights aren't the weakest codex in the game (if you say they're tied with Necrons, that's ok).
Competitiveness isn't about the army. It isn't even really about the army list too much (so long as all the various elements required in a balanced list are there). It is about how the player plays that list. I play Grey Knights, because they match my playstyle. I'm very good at carefully manuvering all my guys and denying the charge and staying out of harms way. I can't do that with Space Marines, because Space Marines are much more static than Grey Knights. I tried starting a Space Marine army when it came out, and I fail miserably with them. Not because Space Marines aren't competitive, but because I don't know how to play them properly.
Plus, I don't think many will agree that Orks are less competitive than Tau. 5th ed hurt tau more than it helped them. I don't think Orks are the best army in the game, but I'd put them in the top half, above Tau.
