Is it better to hold USDT or USDC?

Could you please provide some insight on the current situation with USDT and USDC? I'm really torn between the two stablecoins and I'm trying to make a decision on which one to hold. USDT seems to have a larger market capitalization and wider acceptance, but I've also heard some concerns about its transparency and regulatory issues. On the other hand, USDC seems to be gaining popularity recently, but I'm not entirely sure if it's a solid long-term investment. What do you think? Could you give me some advice on which one to choose, based on their current performance, reliability, and potential for growth? Thank you in advance for your expertise and guidance.
