My first console was the PS1, so I used the DS1 and it felt okay for me. Next console was the PS2 and the DS2 felt like an even better upgrade from the DS1, then I had a brief stint with the Xbox360 and the controller felt way too different as the buttons and joystick placing was different, and it felt too heavy and big that is why playing with it for a long time felt tiresome. Then I went back to own a Ps3 and the DS3 felt great, PS4 and the Ds4 was even better because of its functions.
So I guess I am more of a Dualshock fan because of its sheer simplicity and durability.
