I have seen both, I think they are both fabulous. (My two favorite productions on Broadway at the moment, without a doubt.)
It really does depend on what you would rather see.
A classic score, with a great cast in a new and exciting production, that is emotional and thought provoking.
Or
A bouncy fun score, with a great cast in a traditionally staged big fun all around well recieved production, that is purely for laughs.
I say try the $36 Sweeny Tickets and the DRS lottery, then you have seen both for less than the cost of a regular orchestra ticket.
I stand corrected, you are as vapid as they say.
