When I moved here, none of them had any open spots. Then Abberly Crest and Wildewood made phase 2 and seemingly overflowed the market with apartments, so it seems like there are apartments open in all 3 places now.
Spyglass is the oldest of the three (20ish years old?) with the other two being pretty new...extremely new if you get a place in the newer phase. From what I've heard, you really can't go wrong with any of them. I've had no complaints about the one I've been in. My suggestion is to browse all three websites, see the amenities they offer and the size of the apartments, as well as price.
Another option is to check out the ads on this website (under the classifieds) for places up for rent. If you're able to visit this area prior to moving here, then you could check out which places/areas are good and which aren't so good. You can probably save money and get something of decent enough quality, but it is a much bigger hassle...so if you're ok with the expense and want a safe choice for now, you're looking at the right places.
