Bisq is definitely not the most user-friendly.
Robosats makes it super simple though, just needs a little effort put in to start off (proof of work!), but once you understand the flow, you'll be flying and using it everyday.
Regarding safety, it's quite safe as it uses a well-designed escrow system. Both peers enter a deposit,twhich incentivises honesty.
Mediation by a third-party also becomes an option if there are issues (over hundreds of trades, never had an issue).
Regarding it being in price (usually a few %), this is a premium paid for no KYC. Well worth it.
