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
Iota seems good on paper but still have a lot of trouble delivering things that they promised
Agree with you on modum its one of my favorite small caps coins that made me nice profit

People keep saying that about waves but still so far no real progress on it or work that can be seen,not to mention that no one uses their platform for icos or their new dex 2.0
