What are the best coin join wallets?
Great thinking, I was about to start a similar topic. You should have been asking though also about their pluses and minuses.
Wasabi Wallet, Trezor, and BTCPay Server offer coinjoins that give you complete privacy on your entire balance.
Make sure to avoid Samourai/Sparrow's Whirlpool if you don't want your coins to be trackable
Samourai case is not new. And I've also read that Wasabi's Coinjoin coordinator can check the inputs and may block certain transactions. (I don't know if Sinbad funds are on their list though, I don't know how paranoid one must become.)
All in all, the quest for Coinjoin needs some homework to avoid the cases it brings nothing useful.
