Why?
Rumble 91 was great.
Wrestlemania was subpar, but not terrible (bomb threats
)
Summerslam 91 has IMO the greatest match of at least the 1990s and probably my favorite all time (Hart/Perfect IC Title)
Survivor Series had Taker winning the belt.
and look at the talent level here...honestly.
Hogan (as a draw), Savage, Flair, Piper, Taker, Hart, Perfect, DiBiase, Steamboat, Warrior, Tornado, Rockers, Demolition, LOD...on and on and on.
1992:
The Rumble is obviously a stone cold classic.
Wrestlemania had at least two 4+ star matches (Hart/Piper, Flair/Savage) although Hogan/Vince pussied out of what everyone WANTED to see, it ended up for the better.
Summerslam 92 in Wembley had that awesome Davey/Bret match and a not shabby Savage/Warrior title match
Survivor Series 92 had Savage and Perfect against Flair and newcomer Razor Ramon and a foreshadowing of things to come with a Bret/Shawn main event.
So much talent, so many great matches. Deep, rich tag division. Above average written storylines. Lots of all timers in their prime. Just amazing.
