When you have a hydraulic setup, the autopilot pump does the heavy lifting so you don't have to fight the wheel against the rudder pressure. It makes handling a larger boat feel surprisingly light during long coastal runs or trips across the bay. You just engage the drive and let the pressure handle the resistance of the water against the rudder. It is a relief when the wind picks up and the wheel wants to kick back. Keeping the boat pointed toward the mark becomes much simpler with the hydraulics taking the strain.
