The short answer
USDE scores higher on safety (74 vs 63), driven mainly by collateral quality and disclosure. USDE has deeper tracked liquidity ($3.43B), which is what determines whether you can exit at size. USDE currently earns up to 44.72% — remember that any rate above the T-bill yield is payment for a risk.
If both are fiat-reserve tokens, note that holding both is not diversification: they share the same short-dated Treasury and banking exposure. Genuine diversification means mixing collateral structures.

Which chains support both USDAT and USDE?
+

+

+
USDAT is issued from Not documented with none; USDE is issued from BVI with monthly. Regulatory status varies by your own jurisdiction and by whether the token is offered under a specific stablecoin regime, so treat this as a starting point for diligence, not legal advice.
