I see no reason to compare these two different coins. But I still think that ethereum is the best of all, and that it is one of the most powerful and successful projects.
both of them can be used as platforms. but, however, I think waves are still quite far behind ETH. looking at current IEO developments, most of them use platforms from ETH, and not from waves. in terms of price, I think ETH has a pretty good development compared to the current waves.
Yes, you are right companies are preferring mainly on the Ethereum blockchain because we see large sectors will show more interest in ETH blockchain. The developments Waves are in slow pitch which most companies are not showing interest towards their blockchain platform.
