I've been wondering about this gym too! It sounds good.
I liked Odyssey in Waldwick, but it's under new ownership now, and I'm not sure. I have a friend who loves Retro Fitness in Ramsey.
I have another friend who teaches at Gold's Gym in Paramus. He loves it there, thinks it's very friendly, etc. I've taken a couple of classes there as his guest, but it's a little too "intense" for me.
Ethos in Midland Park has very nice facilities (a won a trial membership there a while back), but I felt the atmosphere of the clientele was a bit snobby. That's just my opinion though.
Right now I'm in a "do it yourself/at home" mood. If I happen to try out Crunch, I'll try to remember to post my thoughts. Please do the same if you check it out. :-)
Edited: I just reread your post. I assumed you wanted an opinion, but maybe you're already a member. Sorry if I misinterpreted!
