this question depends purely on where u play and at what time, there are plenty of live casinos globally where the higher no limit games are of an equal standard to the equivalent stake games online.
Having said that i do believe that people generally do put money in in live games in weaker spots, due a number of factors, number one imo being the fact that live is so slow so the temptation to play that K9 suited in early position, after 2 hours of looking down at 3 8 offsuit, is very real. Online multitabling the patience factor is almost erased, by the sheer volume of hands we can play.
Im pretty sure however that an online pro winning at say a 5 10 no limit 6 max game, would undoubtedly need months of practice in live full ring games before he became a big winner. As the skills required from live to multi tabling online are extremely different.
