nah his biggest main event match was the intercontinental-world title unification match he had against trips^^ The WM20 match wasn't a main event match though
I'd say his biggest main event match was the 1st blood vs. Stone Cold where he won the belt and a close 2nd would be the match vs. HHH on Raw where his mask was on the line
'Spectacle' because they were all in their pomp and and the opponents are big names.
Kane was legitimate main eventer here and didn't need the 'brother feud' storyline to be considered a number one contender. Definitely in the top 5 of big matches Kane has featured in.
