It’s not that optical pros are idiots, it’s that there are so few of them you’ll likely never meet one, and only a true professional can tell they’re full of shit. I can give advice if you’d like. I may be a rando saying Trust Me, but you’re not one of my patients, and we’ll never meet, so I have no reason to mislead.
The Xbox layaout should be the standard. Nintendo changes their controllers drastically every generation, so they have no standard, and even on the GameCube, A was the “default” button. The Xbox controller hasn’t changed the four main buttons in 24 years, and PC followed suit. It’s already the standard, and anyone who would be bothered by a set standard only hurts unification, and will get over it eventually.
