You can make an argument for Punk VS Taker being better than Triple H VS Taker from Mania 27, but this year's match can't measure up to Taker VS Triple H in the Cell, or the Mania matches with Shawn, especially the match from Wrestlemania 25.
The action, suspense, and thrills of the near falls from the Mania 25 match kept me on the edge of my seat the whole time. At Wrestlemania 26 it was probably a foregone conclusion Taker would win after they announced the "win or retire" stipulation, but it was still a hell of a match regardless.
I know a lot of people weren't too crazy about the match from Mania 27, but I still thoroughly enjoyed it. We've never seen Taker look so weak and vulnerable at Mania, and having the medical staff carry him away on the cart was the icing on the cake. Taker had to come back and prove he can still be the man at Wrestlemania without any doubts the following year. The Cell match was full of emotion, drama, and brutality. Others would call it an over the top, ridiculous, and glorified spot fest, but at Wrestlemania 28, two surefire Hall Of Famers fueled by pride beat the living shit out of each other, and they arguably had the best match on the same card as Rock VS Cena. That's an admirable accomplishment any way you look at it.
The match with Punk this year was very good, and again, you can make the argument for Punk VS Taker being the best match on the card (with Lesnar VS Triple H II for competition). Punk was such a disrespectful and cold-hearted jackass, and you wanted to see Taker get revenge for mocking Paul Bearer's death. Not as much drama, and excitement as the Cell matches or matches with Shawn (mainly because you knew there was no way in hell Punk would win), but it was still a damn good match with some impressive counters (i.e.Taker bouncing off the ropes after the GTS, and coming right back for a Tombstone).
The match with Punk was damn good, but from in-ring perspective, I would still put the matches with Shawn and the Cell over this year's match. BUT when it comes to the story and the build, I'd have to go with this year's feud with Punk for the top spot. It was shocking, because you didn't actually think "they would go there," but Punk did. Punk played the detestable weasel role to perfection, the feud had a strong sense of realism for obvious reasons, and you could say Punk VS Taker had the best build and storyline for Wrestlemania 29.
So if I had to rank the matches, this is the order I would choose:
1. Taker VS Shawn Wrestlemania 25
2. Taker VS Triple H Wrestlemania 28
3.Taker VS Shawn Wrestlemania 26
4. Taker VS Punk Wrestlemania 29
5. Taker VS Triple H Wrestlemania 27
