USDT vs USDC: Which is better, trustworthy and more secure to have?

Hey there fellow ethereans,

I have been hearing that Tether has regulatory issues quite often and is not secure. So, is USDC an alternative better choice? If not, which would be the best and most promising stablecoin? Please help. I'm looking for one which is on a scaled blockchain like Solana, etc. to reduce the transfer fees.

Thanks in advance!
