Oh they’re very good controllers! The problem is that they took Nintendo’s button names (ABXY) and transposed their positions. It’s utter chaos, and very hard for me at least to remember that A is B and B is A.
Playstation, by contrast, came up with entirely new button symbols, so it’s much less confusing that O -> A.
The APIs for gamepad interfacing are a total mess now, with some based on button names and some on position (south/east/west/north).
