The best feature for most pro controllers is the additional configurations made possible by back or additional buttons. By remapping your controller, you can put the inputs you use most in the easiest places to activate them. For most, the easiest to reach places are going to be the triggers, the thumbsticks and the back buttons. With that set up, you never need to move your thumbs off the sticks and index fingers off the triggers. If, with your current controller, you’re manipulating your grip to reach buttons, for instance using a “claw” grip, save yourself the agony and splurge for a remappable controller. It’ll probably be cheaper than the physical therapy to fix your mangled hand, too.
