All of Angle/Booker's matches are really good and not remembered, for whatever reason.
I'd say Benoit/Austin from Calgary from Raw in May of 2001...it gets love, but not as much as it should. Also their late 2000 match on Raw was damn good.
Rock/Taker/Goldust/Booker vs. HHH/Un-Americans was pretty good, but no one remembers it (I don't think many people remember the latter part of 2002 because it was just so...I dunno)
Angle vs. Kane for the US title on Smackdown was pretty damn good as well.
All the Smackdown 6 stuff.
We could go on forever.
