The short answer
USD1 scores higher on safety (79 vs 53), driven mainly by collateral quality and disclosure. USD1 has deeper tracked liquidity ($265.49M), which is what determines whether you can exit at size. USD1 currently earns up to 8.74% — 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.
