Michaels/Taker and then Cena/Michaels for me as the two best Wrestlemania Main Events. Austin/Rock would probably be #3 even if I'm not crazy about it (feels more and more like Austin's performance carries it to the heights people perceive it). Lesnar/Angle isn't bad but never grabbed me, HHH/Batista is pretty mediocre, Edge/Taker just does nothing for me aside from the Charles Robinson sprint (though I blame my abhorrence for Edge as a worker for not liking it at all), HHH/Orton and HHH/Jericho shouldn't need explaining. Austin/HBK might a little underrated now I think about it, wouldn't call it close to great but it probably stacks up better in comparison compared to a ton of other Wrestlemania Main Events. Cena/HHH from Wrestlemania 22 is probably my third favourite from WM 21-28, with 26 and 23 being #1 and #2.
WM 20 triple threat would probably be #4 after Austin/Rock, I admire the story but as a stand alone match it hasn't really progressed with each rewatch, if anything its sinking. I probably put that down to the HHH/HBK middle section which whilst it served a dual story purpose, just really isn't going to make my like the match as much as I when I was younger. Pretty shitty drawn out 'epic' brawling between them two just takes me out of it. Benoit is pretty much flawless in his performance throughout and pretty much carries the bruntload of the story and workrate in the match, though the SCM as Benoit has the sharpshooter on HHH will always remain a pretty tremendous visual.
Hogan/Savage might round out my top 5 all things considered:
4. HHH/HBK/Devil's favourite Demon
