Why is DAI better than USDT?

Could you please elaborate on why DAI is considered superior to USDT in the realm of cryptocurrency? I'm particularly interested in understanding the key differences between these two stablecoins and how DAI manages to stand out. Is it due to its decentralized nature, its transparent supply management, or perhaps its closer ties to the underlying crypto assets? I'm also curious about the impact of these factors on DAI's stability and overall trustworthiness in comparison to USDT. Thank you for shedding some light on this matter.
