Bryan Danielson/Daniel Bryan, AJ Styles, Hiroshi Tanahashi, Jun Akiyama, Masato Tanaka, Daisuke Sekimoto, Negro Casas, Dr. Wagner Jr., Chris Hero, Meiko Satomura, Mercedes Martinez, LA Park, Naomichi Marufuji, Rey Mysterio Jr., Katsuhiko Nakajima, Kota Ibushi, & Shingo Takagi all come to mind for being top flight consistent in-ring workers between the 2000's & 2010's. My number one pick would be the great Bryan Danielson/Daniel Bryan himself. It is also AMAZING that he is the greatest worker of the 21st Century, and such a huge portion of his work came while wrestling in the WWE, the most watered down, restricted company possible.
