yeah i think neo is good as he take in the 15 position in coinmarketcap, and actually neo is a good coin for investing.
same like ADA, but i prefer to choose ADA if you just have 150$, because ADA is cheaper from NEO.
Yes, all of them are but if you compare it i think thats where the competition starts. But yeah it is worth investing. But i like ethereum and im putting my trust in it. You gotta trust it buddy
