Physique: Kerry Von Erich or Lex Luger
Mic skills......Flair by a wide, wide, wide margin
Technical ability: Way too many to mention depending on style
Yeah... to me, technical ability is more than just impressive chain-wrestling or high-risk moves. Those things are nice, but they mean more when presented with proper timing, pacing, emotion, psychology, etc. That's what is meant by telling a story in the course of a match.
One of the greatest matches of the last 20 years to demonstrate this was HBK & Y2J's Mania encounter.
Steamboat, Flair, Hennig, and Savage top my list of all-time favorite all-around workers as far as looks, talking, and mat work.
