I would have to go with the undertaker vs brock lesner Match just because of how nasty it got a pure blood bath as J.r would say........
Runner up would be mankind vs undertaker the only thing about this match though was the two big spots in the match otherwise if you really look at it,it wasn't really a match they stopped after he got thrown off,than went back up and he got thrown through the cage than chokeslammed on the tumbtacks than 2 min later the match was over,it's still a classic because of the holy shit factor of seeing him fly over the cage onto the tables and still wrestle
