While there is no comparison in the size of the two, PRG is definitely a larger gym, I would hesitate to call it a better gym. I have climbed at both gyms and have found, in my experience, a very elitist attitude at PRG. Stoneworks on the other hand, while being much smaller, is by far friendlier and more of what I would call a "climbers"gym. Everybody from the staff (who remember your name after one visit) to the regulars are helpful and encouraging. SW will never have the sq. ft. that PRG enjoys, but they have recently finished an expansion that will afford climbers the opportunity for lead climbing. Obviously your current location will have a lot to do with which gym you go to, but for my money Stoneworks is my gym of choice. Just my .02!
