THE 1.5s handle better on-road. Smaller section = better cornering & less rolling resistance. Wider tires means a more cushioned ride but more rolling resistance and mushier in the corners. I tried 1.9 slicks on my bike before I found the 1.5s. Once I made the change, I haven't looked back.
If I was riding off-road on rock, the 1.9s would be very helpful. It's a very different type of riding. You can lower the air pressure much more for grab and yet prevent pinch flats. On road you want more pressure for handling and lowering rolling resistance.
