For a new smart contract blockchain to surpass Ethereum they need to have 1. Launched 2. Have something that Ethereum doesn't have that Ethereum can't copy within a year 3. Have real businesses investing and launching on that platform. As it stands now, Ethereum is way ahead of all the other competitors. I wouldn't bet on any organization catching up to Ethereum until we see those three criteria met.
Lisk has barely launched and won't beat Ethereum with just a clever way to use Java because Ethereum can copy that. Quantum is on proof of stake which Ethereum is adopting soon. And NEO doesn't yet have any real companies investing in its platform other than one ad agency . . . . we can't compare these to the king - Ethereum!
