I think NEM is interesting, but it is a perfect unknown for Europe, America and Australia.
So we know better about NEXT than NEM because NEM is used for Asian people.
However, NEM is alive and if you are interested in it, read this link:

I tested NEM and I like more than NEXT, I do not know how NEM will increase its value, but the notice in previous link remember me the LTC's foundation one or two months ago.
In the other hand, this notice can mean:
1. Its price rises these next months.
2. Its price will be stable (arround 0.00006500 - 0.00007200).
3. Its price will go down and will be stable like prices in point 2.
What do you think? Maybe its a great moment to take positions or it can go down more?
