The short answer
USDD scores higher on safety (69 vs 59), driven mainly by peg stability and track record. USDD has deeper tracked liquidity ($432.82M), which is what determines whether you can exit at size. USDD currently earns up to 3.97% — 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 USDD and USDF?
+
