Inverted or non inverted.
Everyone has their opinion, and they are all wrong. The biggest distinction I have noticed between inverted and non inverted is age. The only thing I can think of for this is that games of years and consoles past used to default to inverted. I even remember there was a time when I noticed more and more games were coming out and defaulting to non inverted.
Inverted is the way. The only way. If you don't play with inverted it seems to be a tricky thing to get your head around, but let me explain the logic.
Joystick goes down, head looks up. Joystick goes up, head goes down.
