I would say NEO. Cause of the smart contract platform they have (just like ethereum). The first ICO of Red Pulse went besides small hickups very well. So there will be much more projects launch their ICO on the NEO platform in future. So I think it's a good thing to have some NEO in your portfolio.

Also the price atm = .0063 very attractive cause imo we willl soon see new ATH past .0140.
