Everybody has their owns I think, but personally my interests go to the hybrid PoW / PoS system with a decent PoW max supply, the fact that it is already implemented (when ETH still doesn't know where it goes), the fair launch and pretty good wealth distribution when 90% of new altcoins come with a 10-20% premine and a TOP 25 (when not top 10) over 50% in the richlist, or their fucking masternode hype creating whales... The TOR integration, and see what the devs are planning on the long run, it seems there will be some fresh news tomorrow, wait and see.
