The short answer
USDD scores higher on safety (67 vs 60), driven mainly by collateral quality and disclosure. USDD has deeper tracked liquidity ($427.30M), which is what determines whether you can exit at size. OUSD currently earns up to 5.96% — 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 OUSD and USDD?

+
Budget three components: the current price spread of roughly 2.0 bps, swap or venue fees, and slippage against available depth ($36.07M for OUSD, $427.30M for USDD). For meaningful size, redeeming with the issuer and minting the other side is often cheaper than a secondary-market swap.
