IMHO it seems that the stabilator would produce the less drag[no hinge line to get in the way] and the quickest response. The full size Cesnas use the regular stabilizer and elavator ,I thnk the reason being they are less touchy[takes a bit of muscle for a stall] whereas a stabilator if set up for performance could get a novice pilot into trouble. A full stall 50' from the ground would be big trouble!
