Castor changes the force required to steer as well

castor plays into handling characteristics, a car driven on 0 castor and 10 castor are going to feel noticeably different
and also plays into the dynamic camber change during steering.
"optimal" is a matter of setting the car up to give you confidence and control while maximizing grip.. so the answer is "it depends" :p
