I'll be short and to the point: Across all the time you've been a fan, which Mania (or Mania's) would you consider a 10 out of 10 for excitement heading into the show? Follow up question is obvious: What Mania or Mania's would rank the lowest for excitement leading up to the big show? You can exclude Covid-Mania wiping out the audience in 2020 to make it a little more fair. 
I was so excited as a kid for Wrestlemania V that I had trouble sleeping leading up to it so I’d have to go with that one.  In the modern era, probably 20, 25 and 30.  The one with Shawn-Taker II was really well built as well. 
For worst, the one with Roman and HHH ranks far down for me.
