Both Coins have huge potential for growth.I love the Waves DEX but Ethereum is the currency for ICO's.
I would buy Waves for 1 ETH and hold the rest for a promising ICO.
Waves is good, but the only problem is that they are not having a good marketing team, no one is aware of the real potential that Waves has at the moment.
Look at ada, they do not even have a good project and they are on the top five without doing anything.
