Most of my stablecoin is on BUSD. USDC is also good option but I prefer BUSD since I always trade on their exchange, and also they have many trading pairs for their own stablecoin so I don't have to worry converting it from one stablecoin to another. Binance is currently the most reputable exchange and they have a lot of funds to support their stablecoin. Depegging BUSD won't happen that easily as it is backed by a real entity unlike what happen in UST and LUNA.
