I'm severely of two minds on this.
From purely an in-match/psychology/performance standpoint, it was Punk/Brock. The psychology was better throughout. It was better back-and-forth. Even though the conclusion was foregone, it was a creative way to get to it.
While the Bryan/Cena match was a little inferior (and I do mean a little), the execution of the post-match scenario, everything from Cena's reaction to losing to the post-cash-in celebration between HHH and RKO was perfect. It couldn't have been done better.
So, I'm truly neutral. I think they were the two best matches of the year or two of the best three (with Punk/Undertaker at Mania being the other one).
