A lighter trigger pull generally yields better trigger control, less disturbance of the sight picture when pulling the trigger, smoother release. It may or may not affect trigger reset speed, depending upon the design of the trigger.

Trigger pull on Olympic competition firearms is measure in ounces, not pounds, all for the above reasons. I have two match pistols with pulls of 18 and 14 ounces; A dream to shoot.

JP springs yield minimal reduction unless one takes the time to polish the mating surfaces of the hammer and trigger hooks, BTW.
