Grin is lightweight by design, obtaining most of the privacy benefits (hiding amounts and addresses) while staying 4x smaller than bitcoin. The extra transaction step adds robustness, letting the receiver state and sign for the purpose of payment (e.g. the item purchased or the service rendered). Monero obscures the tx graph with decoys (effectively only 4 as recent research by Rucknium shows), which cuts corners compares to the much stronger privacy guarantees of Zcash's shielded txs.

Grin stays small by sacrificing privacy. Hiding amounts and addresses isn’t enough if transaction linkability depends on network conditions. If privacy weakens when volume drops, that’s a design flaw, not a feature. The extra step isn’t robustness, it’s friction. Payments should be fire and forget, not a back and forth process. Monero works because it just sends, no hassle. And Zcash? Please. Over 95 percent of its transactions aren’t shielded. What good is stronger privacy if almost nobody uses it? Monero may have only four effective decoys, but every single transaction is private by default. A privacy coin that relies on opt in privacy isn’t a privacy coin, it’s a compliance coin.

  Monero gains a little privacy by sacrificing scalability. Grin is designed for simplicity, scalability, and fairness, not privacy at all costs. In such a design, the optional CoinSwap protocol for untraceability is a scalability preserving feature. Ensuring the correct recipient and purpose of payment is not only robustness, but also added privacy since payjoins obscure the direction of payment, something Monero lacks. With only 4 effective decoys, Monero's privacy is deficient, while Zcash shielded txs enjoy far superior privacy, independent of all the transparent txs.

    What’s better: a bulletproof safe that nobody locks or a well-worn disguise that everyone wears? Grin prioritizes scalability over privacy, which is fine if you don’t actually need strong privacy. But let’s not pretend optional CoinSwap is a real substitute for built-in, default anonymity. Privacy that depends on extra steps and high network usage is fragile by design. Monero doesn’t need payjoins because every transaction is already private. And calling 4 effective decoys “deficient” ignores that Zcash’s superior privacy is irrelevant when 95% of transactions don’t even use it. If privacy is optional, it’s just a feature. Monero makes it the foundation.
