I havent tried BUSD yet because I mostly uses USDT every time that I do have transaction and for the reason that USDT is ERC20 and TRX20 connected that makes my transaction easier.
Not TRX20, but TRC20, and not only that, the USDT token is also connected to the OMNI network which this option can also be used by anyone who uses it, so it is only natural that USDT is ranked well as a stable token because clearly there are so many uses in the crypto space.
