Buying it at one of the non-Times Square booths is helpful cause you know the day before you've already got tickets and don't have to deal with the throngs at the Time Square booth. Other than that, it's impossible to predict whether the tickets or discount will be better or worse. I've gotten very good seats at one of the off B'way booths and other times rejected a ticket in the afternoon for an evening show at South Street I didn't feel was that good only to try at the Times Sq. booth later on and get a better ticket. A lot depends on whether the show releases better seats they couldn't sell closer to show time which would be sold at the Times Sq. booth. As far as the discount, I've seen it start at 50% at the Off Broadway booths and when Times Sq. starts, it's 40%. I'm sure the reverse has happened but I don't think it happens as much. And with Ken Davenport pulling the strings, a guy who seems to change the rush rules on a daily basis, even if there was an established pattern, he'd break it. My advice is if you go to the off B'way booths and they have it, you like the seats they have and are happy with the discount and don't want to take a risk you might get shut out at Times Sq., grab them. If not turn them down and wait for the Times Square booth understanding there's a risk they might sell out of them before you can get to the window.
