In each project you will find advantages and disadvantages. The Waves project is not as popular as Ethereum, and there are not many projects in partnership with it. Now this problem - the involvement of the masses of people is relevant for all projects. When people understand the value of decentralized payments and contracts, then the Waves will become much more expensive and successful.
From my multiyear experience with waves, waves team doesnt partner with outside projects. All the projects supported by waves appear to be internal or closely related to waves team. neutrino, better tokens, vostok, liquid, tradisys, all appear to be russian and I have never seen a non russsian project supported economically by waves. So there is little chance of getting ETH level or even any significant funding for a waves project. Not sure how they can improve their support now that waves themselves are no longer one of the best funded teams.
