I believe that upcoming catapult update will change everything and NEM, a truly fantastic and cheap cryptocurrency with a unique and progressive proof of importance concept will challenge ETH at it's own game and replace the damned Buterin's $hit coin, which only old grannies with their cryptokitties find useful
eth is more established than nem and that won't change even after the update I believe. there are some other platform that you could argue are better than eth and you might be right. But in terms of usage, eth is still miles ahead of their competitors. Their community is large and that makes difference.
