Is DAI safer than USDT?

Could you please elaborate on whether DAI is indeed safer than USDT? Both being stablecoins, they serve similar functions in the cryptocurrency ecosystem, but their underlying mechanisms and collateralization models differ significantly. DAI, being a decentralized stablecoin backed by MakerDAO's CDP system, seems to offer a degree of decentralization and transparency that USDT, a centralized stablecoin issued by Tether, might lack. However, USDT's widespread acceptance and integration within the crypto ecosystem cannot be ignored. So, what factors should we consider when evaluating the safety of these two stablecoins? Is it solely based on their decentralization level, or are there other metrics like collateralization ratios, audits, and regulatory oversight that also play a role? I'm curious to hear your thoughts on this matter.
