Austin/McMahon was revolutionary for the business, as was Rock/Austin to a lesser degree, but from a personal standpoint I enjoyed Austin/Bret. They dragged Austin/McMahon much longer than they should have, and there was never really a huge blowoff. Austin/Bret is my all time favourite fued, namely due to the Canada/US angle and the mark inside me truly hated Austin at the time - back in the day when RAW was must watch TV.
