Crunch, I believe, is more expensive. But they have a much better selection of classes than NYSC, that's what they're known for. I don't take any classes so it doesn't matter to me, but it may to you. I'm not sure about Crunch, but NYSC has a citywide membership that allows you to go to any NYSC in the five boroughs. They're all over the place, which is useful for me because i'm in different parts of the city on different days. Also, with NYSC, there is no contract to sign, it's month to month membership and you have to give 30 days notice before cancelling. I'm not sure if Crunch has the same thing. Maybe someone familiar with Crunch can help you out.
