I have a membership for Goodlife and it's the best gym I've ever been to so far. I've been to 4 different locations, and they have all been great. Like you said, they do have a lot to offer. Their equipment selection is great and their amenities are even greater (classes, squash court, sauna, etc). I would recommend getting a membership there.
Oh, and they always have orientations going on for different things (general, cardio, strength training, etc) so it's always there if you need it along the way.
