Either Randy Savage or Bret Hart. Savage got to carry the world championship without being in Hogan's shadow (though perhaps a trivial thing to complain about since the Mega Powers angle >The Ultimate Maniacs) and Bret Hart had a great Intercontinental Title reign and we got great matches out of his reign like with Piper at Mania and British Bulldog at Summerslam. He won his first world title and we got a good (but IMO, not great) match with Flair and then a pretty damn good match with HBK at Survivor Series (preceded by an awesome pre-match promo from Michaels on top of it.)
