Depends on what I'm doing. Larger buys I use bisq. Smaller buys, I use Robosats.

Bisq is primarily on chain. Robosats Can do on-chain transactions, but is primarily a LN platform.

RoboSats is basically the Wild West. I've never really been scammed on it except for once for like a $50 buy (imo That's a damn good track record considering I've used it at least a hundred times by now.) Bisq It's a little bit slower due to its on-chain nature, but it also has an escrow service and some basic mediation, which thankfully I've never had to use.
