Well these are our opinions. To me a technical wrestler is a master of the ring, a swiss army knife of wrestling. He can do it all and can adjust his style depending on his opponent or the situation he is in. Steamboat and Bret Hart were the epitome of this. Again, this is only my opinion. Wrestlers can fall under these categories:I've said this before, to be honest, "technical wrestler" doesn't really mean anything the concept is way more broad than high flyer, brawler, or hardcore. So what you base your opinion on who is the best at it depends on how you categorize technical wrestling.
For example, I have no clue why Bret Hart or Steamboat could be categorized as "technical" when most of their careers they weren't mat based wrestlers. Same with a guy like Flair.
Technical (Hart, Steamboat, Curt Henning)
Brawler (Cactus Jack, Austin, Taker)
Grappler (Malenko, Benoit, Steiners)
High Flyer (Mysterio, Hardy Boyz, Sabu)
