1. Iota - great support from the industry. Some advantages against Blockchain and DAG, e. g. no fee for transactions
2. Modum, real usecase for the logistics industry. First partner: Swiss post
3. Waves, the real better Ethereum
As for waves - they have slow and lazy team, almost nobody uses their service.
Do you remember any successful ICO on Waves (except Wagerr)? I don't
I've bought also Oceanlab, and in the last days was the ICO from paytomat. i was too late to got some Tokens. Waves is a hidden champion. The question is, they use their potential?
And i'm absolutely longterm-oriented.
