Yes, the "American Dragon" Bryan Danielson (Daniel Bryan in WWE) is hands down the greatest in-ring performer on television today, and I'll even go as far as to say he's the best wrestler in the world (sorry Punk).
Ever since coming to WWE in 2010, Bryan has produced numerous five-star matches and has yet to produce a less-than three-star match. He's not as much of a spot-guy as, say, AJ Styles or John Morrison, but he more than makes up for this with his highly adept submission wrestling as well as his chain grappling.
Before coming to WWE, Bryan was known for his stellar work in ROH and other indy promotions and was even then called the best in the world by many fans. Upon coming to WWE, though, many feared that due to Bryan's size, he would be misused by the company and perhaps even become an Evan Bourne-like jobber.
Even though he achieved midcard success quickly by winning the US title, this fear was still present in our minds. However, Bryan proved us all wrong when he shocked the world at the recent Money In The Bank pay-per-view by winning Smackdown's Money In The Bank Ladder match. (He may or may not end up losing it to Wade Barrett, though.)
All in all, while Bryan may not be as much of a complete package as CM Punk or AJ Styles and I myself am not the biggest Bryan fan, neither I nor anyone else can deny that he is the best wrestler on television and perhaps the best in the world.
If you won't take my word for it, though; I recommend watching some of his best matches, which include:
Bryan vs Dolph Ziggler at Bragging Rights 2010, Bryan vs Austin Aries in '09, Bryan vs Nigel McGuiness in '08, Bryan vs Chris Jericho on NXT and Bryan vs Homicide in 2006.
