The short answer
USDG scores higher on safety (92 vs 60), driven mainly by collateral quality and disclosure. USDG has deeper tracked liquidity ($697.15M), which is what determines whether you can exit at size. USDG currently earns up to 8.81% — 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.
