Stable coin differences? (USDC Coins / Circle, GUDS Twins, TUSD – Trust Token, PAX – PAXFUL, USDT – Leash)

Lately, there were many stable coins. What are the differences of each? So far, I know that tether (usdt) comes from the US banking system and everything else is regulated in the US banking system. I also read that the USDC and the GUSD have a backdoor system to freeze and hold accounts if they so choose. I was not sure if PAX had the same thing. What are all listed advantages / disadvantages of each stable coin?
