Disagree, mainly because of how many times the ball was dropped. I can't call something that botched the best ever. Yes, it ended with a feel good moment, but:
-Bryan got fucked over to the point it ruined about 3 straight PPVs, and others later on
-WWE never had any intention of following up his redemption, it was supposed to be handed to Batista
-the 2014 Rumble was a disaster
-Bryan was kicked out of his own storyline for Big Show, who also was given his chant
-Bryan was put in a feud lower on the card, out of the main event, where they turned him heel
-It was only due to fan backlash that the WWE was pretty much strong armed into giving in when they never planned on it, which makes the whole WM30 ending kind of a fluke
I'll give them credit for ultimately making the right decision in the end. However, this whole story highlights the WWE's incompetence, more than anything.
WM17 Austin vs Rock is still their
#1 . The 2 biggest stars of that era going head to head in the main event of their biggest show, built up as 2 guys wanting to be the best. Combine that with the fact that back then, they had a clue, and the fact that that match was their goal all along, and that solidifies it.
Not taking anything away from Bryan, of course. Everything that got fucked up was out of his control.
