I will go for ethereum.
In terms of transaction per second CMT is better but CMT is still under development, so if they could pull it off then they may have a chance to compete with ethereum.
These are my concerns about CMT.
- High Supply (1bln and increases 8% due to POS)
- Privacy? (At the bottom of the table "Shared data services" Will these be public? Identity, credit history, reputation, financial statement)
