With the audit involved, I think the most trusted stablecoin would be USDC and BUSD. They had a documented record of audit that shows their stablecoin is full backed by $USD and it was proven that logarithmic stablecoin isn't that stable, just look at what happen to UST, and USDT had caught lying to us regarding their statement that they are fully backed up by USD.
well, I also think that BUSD has great trust, especially when they have a trusted CEO and team and a clear company, making trust in people grow. but still, of all of them, USDT has the most volume, and since the UST incident, I've been thinking about keeping coins stable in my wallet for too long. well, rather than stable coins, maybe I prefer Fiat, or other more popular coins like bitcoin or ethereum. but beyond that, I've only used USDT and BUSD so far for stable coin.
