from a UX/UI perspective it is the best wallet for noobs, if you have sats on Muun you can pay pretty much any QR code [minus some LNAuth operations] that would appear in the bitcoin ecosystem.

very little friction to go from getting sats from a friend, to being able to pay an invoice or to a on chain address.

QR codes are still such an underused and underappreciated piece of tech, here in the west. I know a lot of the Asian countries use QR codes more frequently.
