We have seen a lot of fuders trying to victimize the usdt project just to make it loss it value. Usdt had been a good project since and they have establish a good reputation but presently is like there are haters that are trying to bring it down. BUSD is also a good project that was established by Binance and it is doing very good in the market now with good volatility and liquidity. It had been stable since and it is going to be a good project so far.
Yeah, I saw both USDT and BUSD carry a fair amount of risk. Some might think this one is better than the other but I think the best course of action is that you should use both of them. When one got into issues, losing its rate, the other will mitigate the risk for you.
