Not enough to confidently comment...

I'm bullish on Bitshares due to what seem like solid fundamentals.

I've got a little bit of Nem cuz heard from a trusted friend there's been some excitement building in its community of developers and has some interesting prospects in Japan.

Waves was the first or second ICO I bought into, though didn't know much about what it was at the time. Ended up selling cuz progress was super slow and didn't see results validating keeping my funds locked in it.

Don't know much about the other two.
