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
Other successful but lesser known ICO on waves includes Oceanlab, ZrCoin, and Starta.
And Waves is not lazy, thy just lack a good PR department for churning out hype
