Best rivalry was with Kane, some weird stuff that was over the top but was not corny, it fit in well with his gimmick and IMO was a great storyline.

Best match IMO was Mankind in Hell of a Cell, one of the matches I will always remember.

Not to forget he had one of the most dramatic and face changing factions of the WWE - Ministry of Darkness. At one time this faction nearly had half or more superstars on the roster in it. It also helped bring the WWE from under danger from WCW at the time and will IMO be one of the best of all time.
