The short answer
USDY scores higher on safety (88 vs 61), driven mainly by collateral quality and disclosure. USDY has deeper tracked liquidity ($2.21B), which is what determines whether you can exit at size. USDY currently earns up to 4.11% — 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.
