Controllers matter, especially if you're making the shift from console gaming, where choice is limited, to PC gaming, where the only thing stopping you from grabbing a specific controller is money. But while every controller is trying to give you an edge, some do a better job than others. Some feel more comfortable, some allow you to do more, and some just look cooler. So I spent the last few weeks playing a lot of video games to find the very best controller you can buy.
