The short answer
USDS scores higher on safety (88 vs 54), driven mainly by collateral quality and disclosure. USDS has deeper tracked liquidity ($7.78B), which is what determines whether you can exit at size. USDS currently earns up to 5.82% — 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.
