Every coinjoin implementation has flaws. For now wabisabi is the best one. Would be great to have ashigaru compared the same way.

My comparison of the three major forms of coinjoin in active use: Wasabi, JoinMarket, and Payjoin.
tl;dr: Payjoin is cool and you should use it if possible. JoinMarket unfortunately has a serious flaw. Wasabi is the best overall and provides decent privacy.

If people really want a ashigaru review, I charge $150/hr. Total for the coinjoin comparison blog post was about $8000, spread out over a few months. Most of the hours went into examining Wasabi (and writing about it).
A reasonable price to refer for ashigaru enthusiasts. Thanks!
There's intresting bitcointalk on ashigaru faults.
