We chose to use Smart-Chain also. Like it or hate it Binance IS the largest exchange. Almost too big to fail type deal.
The drawback to BSC though is no bep20 tokens will ever be listed on CoinBase probably. Not sure if because direct competitor to Coinbase or Binance is outside the US.
Overall gas fees stay pretty cheap, its pretty reliable from what we have seen in 6 months and more and more people are using it or atleast know how to purchase BNB.
