There is no such thing as a " good setting" it will all depend on your machine, what motors etc.
Faster acceleration will allow your machine to reach the programmed feed much quicker so will almost certainly reduce cycle time, especially when code with small moves is used. It can be quite a dramatic change and can often cut cycle times drastically thus it is often much better to have less Velocity in motor tuning if it allows you to have greater acceleration.
As an example when I had a Bridgeport with steppers I could get 2500mm/min rapids but only an acceleration of 40mm/s/s. I reduced the Velocity to 2200mm/min and that allowed me to get the acceleration to 120mm/s/s and that halfved the cycle time on some jobs.
