For me, the most reliable option for work is Ethereum. Now it is becoming the basis for the work and development of many promising ICOs. But I admit that in the future the situation may change - after some updates, the Waves platform may improve its position.
Waves seems to me difficult to use and we never felt comfortable using waves. On ethereum platform it is easy to use and it is fast price also low. And there are a lots of projects who used ethreum there is only few projects who used waves to start their project.
