If you just mean about Muta himself, then I'd say he is one of my top 5 Puroresu wrestlers. I know people complain that now he is holding back the younger talent, but he can still put on a good match. His ability to wrestle two different styles is just amazing, and he was one of the most talented wrestlers in Japan during the entire 1990s.
Keiji Mutoh is my top puro star of all times. His energy, his charisma, his technique, his beautiful Moonsault...
On top of that you have his Great Muta personna. Man he was the best! I loved his transition from Mutoh to Muta in the late 80's early 90's. And his BATT comeback was great. Shows that he can still fight.
Hiroshi Tanahashi reminds me SO MUCH of a young Keiji Mutoh ...
