Always choose those stable coin which is backed with fiat and stay  away from those Stable coins which are backet with algorithm. We already seen ust and Dei crash.
In my view most trusted stable coins are Usdc,Dai and Busd. These stable coins are backed with fiat with strong Support by Etherium and Binance respectively. Government of England also looking to legalize Usdc and it's good for this Stable coin.
