I have been testing Robosats vs Bisq for speed and liquidity today.

Robosats was faster and cheaper in fees. (Paid 4% above market) Bisq had more liquidity and better overall price despite paying higher miner fees. (Paid 2% above market)

I used an instant payment method for both, so trade was completed in ~1 hour.

There is still some room for improvement I suppose... if market makers were online 24/7 you could probably complete a Robosats trade in 5 minutes. Bisq is limited by waiting for block confirmations.
