The short answer
USDT scores higher on safety (76 vs 53), driven mainly by collateral quality and disclosure. USDT has deeper tracked liquidity ($3.55B), which is what determines whether you can exit at size. USDT currently earns up to 17.67% — 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.

Combine that with the redemption channel — USDT: gated; USDW: market-only — and size trades against the primary window rather than the order book where possible.
Can I earn yield on USDT or USDW?
+
USDT currently shows the higher rate at 17.67% via azuro · Polygon, against no tracked rate for USDW. Neither token pays interest by holding it in a wallet: the yield comes from lending, liquidity provision or a wrapped yield-bearing version, each with its own counterparty and contract risk.

Budget three components: the current price spread of roughly 3.2 bps, swap or venue fees, and slippage against available depth ($3.55B for USDT, $0.00 for USDW). For meaningful size, redeeming with the issuer and minting the other side is often cheaper than a secondary-market swap.

+
