Gamepad vs Joystick

[Robotic Pope]

I was talking to Brickster tonight about the joysticks for consoles. Do they all have a circular motion like a gamepad stick or are there any PC ones that can be used for PS3 that have a full motion in every axis so there is a square shaped motion at the base of the stick with corners at top right, bottom left and so on.?

If there was a "Square shaped" stick the user would get a huge performance boost in a dogfight by being able to use full ailerons and elevators and vice verse at the same time. Would make barrel rolls and rolling scissors much easier. Now Ive realised this I feel very restricted with the "Circular" shaped gamepad sticks.
