I'm not too familiar with modding controllers. but playing a friends Xbox one last night... it was painfully obvious how much better the analog sticks are in not only their accelerated sensitivity... but the grip as well.... was absolutely impossible to slip on that controller... perfect for FPS. even though it was only cod we were playing it felt 100x better than my experience with the DS4 and Destiny.
The only downside to the DS4 vs the X1 Controller though... but a very big one for most games.
Anyone know of any recommended alternatives? the material/grip is horrible.
