It is too soon. The fact is, that NXT is in difficult position, even though It seems to be best platform right now. Yes the stigma is huge problem.
NEM will no have any stigma, so if It delivers what we think, It will in my opinion overtake NXT.
What does it hope to deliver that makes it much better than NXT? I know this sounds like a defensive attacking question but it's not, I genuinely want to know what is the best at least on paper if all things promised are delivered?

Success is driven by people's perception and IMHO NXT has failed to gain that people's confidence with their initial distribution.
I wouldnt want to invest in some coins, which I know could be brought down to zero value if some of the inital investors get greedy.
I still think some of the investors are waiting for the price to go up a bit more to dump their coins.
