Practically both are great. So is JM for the most part. Just be smart with UTXO mgmt.

it's not as good. Ashigaru gives you KNOWABLE entropy, Wasabi still doesnt afaict. That is, you have no idea how much randomness is being added through the coinjoin. coinjoins are hard and wasabis design is trying to do a lot.

Wasabi is way better. There's no common input ownership leaked, no toxic change outputs, and 100x more liquidity.
