Ugh. Talk about the least worse choice...
Visit all three. See which one is most convenient and has what you like to do.
Planet fitness - usually has decent machines. Free weights are the issue. I can't stand their no judgement zone policy and I think they prey on the weak. But, you do get guest passes and can get an unlimited memebership that you can use at any PF. Good deal if you travel a lot like I used to.
Crunch fitness - my experience their equipment is subpar. I bent a barbell one time squatting while there. Guy was like it wasn't a big deal and he'd just go to Walmart and get a new one. Not much variety and all their equipment, to me at the ones I visted, seem like something you would get at K-mart.
Anytime - the ones I've been to seem almost like a decent hotel gym. You can get a lift in but doesn't have what I needed at the time. Their equipment seems decent but not much variety either.
Bottom line, all three will work. Neither of the three are my cup of tea. Again, visit and join the one you like the best.
