I like both of the coins Tron & BNB. The primary blockchain for these are Tron network & Binance smartchain respectively. Both takes very less fees as compared to ether blockchain. Actually the thing is the benefits & functions of blockchain. BSC supports Defi, dApp, NFT, etc. Many new comer projects choose BSC for the easy use with less fees which become helpful for them in their investors also, this will help in NFT, dApp, etc. Binance's native token BNB which has a great future & this will be huge in future. So, many of projects choose BSC.

I believe Tron will have a good future but it will take some times if Justin will put some more effort & development in it. Then many projects will go towards Tron blockchain. Another scenario is, if the transaction fees of BSC will go highers then project may think about Tron blockchain but there are more competitors such as Solana Blockchain, Cardano Blockchain, etc. For transaction I like BSC in final.
