I don't think anybody's saying the 101b sucks, I just think a lot of things people were looking for the 101b to do, were remedied in the 20th. Less filtering and compression, tighter bass response, easier to dial in, excursions and bright switches more effective, better clean channel, plexi mode boost for more gain, more cut and a more usable red channel. Like Steve_k said, though, if the 20th didn't exist I'd still be happy with a 101b...The blue channel blew my mind...it was the elusive sound I was searching for and turned me on to Bogner.
