It’s usually good to switch between them. For instance the neck pickup gives a more cleaner sound when sweeps or scale runs up or down. However, playong further up the neck on lpwer trings it doesnt have the punch that the bridge pickup would have if that’s what you are going for. Also in most cases neck pickup doesn’t too good with pinch harmonics where as the bridge would never fail (unless you fail). So yea use both depending on the sound you are trying to make.
