They really didn't improve it enough. Better sticks more like the XB1 controller would be a huge improvement. The cheap slippery rubber they use feels poor in comparison. The first thing I did was put some XB1 sticks on it. Plus the plastic used on the triggers feels cheap and low quality.
In terms of shape and ergonomics the DS4 is my favourite controller ever but I just wish it had better materials.
