-The light bar is shifted to just above the touch padI still have a launch DS4 (switched out the thumb sticks with Xbone Ones) is there any reason to upgrade to a newer controller? It's been a few years, did they make any enhancements with them?
-The rubber on the sticks is more sturdy/refined
-USB communication (you can play games with a USB cable and that will help a bit with latency).
-Better battery life (perhaps a minor difference though).
I think those are the most noteworthy changes.
