If you've used Wasabi or Sparrow please share your knowledge. What's the best & worst experience using them? What advice would you offer friends about these mixing wallets?
Sparrow is way better Bitcoin wallet than Wasabi, it has better use interface but I wouldn't say any of them is better for mixing Bitcoin.
You can't use Sparrow for mixing coins until you run your own node and connect it with Samourai, that is not exactly user friendly for most newbies.
Wasabi on the other hand is using controversial coinjoin feature with coordinator, but it's very easy to use it out of the box, even for newbies.
But if I had to exclude mixing part than I would have to say that Sparrow is better overall Bitcoin wallet.
