All of those matches are easy ****3/4 - ***** classics.
How do you rate HHH/Taker matches the last two mania?
I have no problem with people putting any of those matches at ****3/4-*****, I just don't. Still all classics though.
As for your question, here it is:
Taker/HHH WM27- ***1/2
Taker/HHH WM28- ****
Honestly I tried watching Taker/HHH WM27 some time ago, and I just couldn't sit through it again. The storytelling, while good, is trumped by the storytelling in WM28 and honestly that match just makes WM27's seem like nothing. Personally I never thought WM27's storytelling was as great as others made it out, though it's still some very good stuff. The only part of the match I could watch over and over again is the tombstone from HHH to Taker and the kickout with the crowd reaction. JR's commentary, the crowd, everything was perfect in that moment. Besides that though the match honestly just isn't fun to sit through anymore. I never had a high opinion on it even when everyone was calling it a ***** classic right after it happened, but now... meh.
WM28 was the perfect end to the Taker/HBK/HHH arc and did a far superior job in the storytelling department. I think it lacks in all the departments it did the year prior, but not as much (pacing, wrestling/action), but where it excelled, it did better. Now I don't think it's an all-time classic like many others do, but it's an awesome match. I don't think I'd have it in HHH's top 10, and I certainly don't have it in Taker's top 10, but it's what storytelling in wrestling is all about.
Edit: In additions to the matches stated above, pretty sure Benoit/HHH/HBK WM20 will be in his top 5.
