This Y has great racquetball courts and is located right in the middle of downtown, so if you work or live right in town, it's perfect. If you live out of downtown though, parking can be a pain, though it is available in a nearby garage for pennies.
This Y seems to be in the "middle" in terms of quality compared to the other two. It also seems to be less crowded than the nicest south location, particularly on weekdays. So, if the location is convenient, I would highly recommend this Y.
