At the end of the day they're just glyphs though. Maybe letters in a clockwise alphabetical order is the most intuitive for someone who has never used a controller before, but I've never seen anyone complain about the PS buttons layout after the initial "where the fuck is triangle" phase... except for that Japanese standard where X is "cancel" and O is "confirm"... because they deviate from what we are used to (and actually mimick the Nintendo layout regarding A and B placement, interestingly enough)
