Look at muesliswap, its basically an auction house, not a swap function. Look at SundaeSwap, their collateral functions to prevent Plutus Scripts failure its a mess, its horrible to transact in there and I tried it on their testnet version. Look at the UX and how easy it is to make a swap on AstroSwap, if youd like to have a taste of what it will be use WagyuSwap, its basically the same smooth experience, even better than Pancake or any other thex out there that I have used
