Samourai isn't perfect, but I would readily recommend it over Wasabi. If you do use Samourai, then it's important to enable Tor and link it to your own node to maintain full privacy.

For desktop, then the easiest option is to use Sparrow (also with Tor and your own node) to mix with Samourai's Whirlpool. The best, but more complex, option is to run JoinMarket.
