For me both are good and best on their own blockchain and use cases. Binance is bigger and hotter than Tron but both are best with lower transaction fee. It just happen that in Tron we can see the limited projects and not so much development compare to Binance Chain with lot of games, dex, DeFi and NFTs. I do believe Tron will have more empowerment to make their products and tokens more valuable than yesterdays.
