Ya, I've seen almost nothing but clones. NXT is basically a clone that makes some improvements but in principle, is the same.

Mastercoin however with allowing chargebacks is an real alternative that solves for alternative uses, but MasterCoin is built on Bitcoin and uses BTC as collateral. So BTC is still the undisputed king for the next 4 years imo. Although I haven't spent the hours and hours of research to really call myself a student of the whole altcoin landscape.
