I suggest you look at Sterlingcoin as well, they have a great roadmap and useful features coming + the developers are trustworthy (you can even call them if you want).
Also, you might want to look at GEMZ, but I'd recommend you to wait on that, until they release the iOS app and get everything running without any bugs.
Gems looks interesting and to me seems one of the only coins with some actual potential and real world use. I think some sort of decentralized social network or messaging service could really take off as who doesn't want to get paid to use one?
