My only question about hydro- steering would be the feel for blowouts missing. I like knowing that when making a pass, that when I bump up too much, I can feel the wheel loosen up. I would think you could feel the same in Hydro-steering, but I don't know. Also, I am used to having the trim on the wheel, Most hydro systems I've seen had the turn signal style trim.
The good thing would be not having fighting the wheel torque to the left when you have your engine jacked above the pad.
