Good wishes to both tron and waves for this initiative.
You have asked will this become more popular than the defis on ethereum blockchain?
Well ethereum blockchain and ecosystem is so broad and so well adopted that it is hard to compete by even some partnerships between two projects but still i would encourage tron and waves as it will be good for the market, investors will have more options and we will have a healthy competition.

Yes, there will be much more opportunities, I think so.
Also, the fees are already much lower there and the transaction speed is much faster than on the Ethereum blockchain.

But whether their common blockchain will become more popular, seriously, is a mystery.
