I prefer usdt, specifically I myself do not really understand between usdt usdc and several other stablecoins because almost all stablecoins have almost the same characteristics. but I often use usdt whether it's to store assets or just as a coin swap from an exchanger to a wallet.
I will also say that USDT is based, it’s marketcap is comparatively high and also it’s a well popular coin.
The price along with all the coins mentioned in the OP are same but yes availability of USDT is more if we compare it with the rest.
USDT currently can be the ideal stable coin to do a stable or reference trade , but yes people have different opinions ans choice.
OP I suggested you about my experience and knowledge on the matter that you asked, rest is now up to you . What you want to choose or decide.
