It really depends on for what purpose do you need your tokens. Because with ethereum you have many people that have built the infrastructure with many smart contracts and dapps and it might be better in a sense that you can find a lot more information, ask many more people for help etc.Although ETH has it's own decentralized exchanges which other people have built such as EtherDelta.
On waves it is much easier to deploy your tokens as you can do it with simple GUI and thus it makes it faster to deploy tokens. On the other side Waves might be cheaper. Waves might be better in a sense of volume, because there is only one DEX where most of the people trade, where as within ethereum you have different exchanges with different volumes.
I completely agree, it's funny how people get so tied up on the price of something thinking that only the price and market movements of a coin justify its usefulness. Have you ever tried to develop or use a dApp? If not I would research how too first before I would put any money into it so you could see the use case yourself. ... If you yourself can't justify using it, what makes you think it would have any value to anyone else you personally know?
Edit: I think this is more suitable for altcoin discussion sections
