If you are looking for stable coins there is no other than great and it is only USDT. But I have to ask a question first, why you want stable coin/s?
Because for the fact that stable coin/s won't make you profitable than those volatile coins just like Bitcoin, Ethereum, and the rest. If you are looking at this thing (profit), of course, I will invest these coins rather than to stick my money into no moving value coins.
Having this stable coin is only having the assurance that we can't lose our money and less risk but not good for investment, unless if you are just preserving your money in crypto.
USDT is not a great stable currency although it has more trading volume than other currencies. It often encounters trouble with auditing, about fraud allegations.
usdt has a huge trading volume and for the controversies around it, I am still amazed it commands such huge volume especially with respect to the fact that its backing is ambiguous on like usdc and busd backed by dollar
