Broadway is no more conservative than the West End, look around at what's playing. I agree, but I think one key difference between the West End and Broadway is that there are other theatres in London like the NT and the Royal Court and the Donmar that aren't West End theatres but are often thought of as part of that group, and a huge amount of the quality theatre is either playing there or has transferred directly from there - not West End theatre, but often grouped in with it, including at all the main award ceremonies. From what I can tell, and I could be wrong about this, the difference between commercial and non-commercial theatre is far more clear in New York than in London.
If you compare the commercial West End with the commercial Broadway, ignoring the subsidised theatres, then neither is better than the other (and both are pretty grim).
