Everyone I have spoken to, including Stan at Schiada, says they are very responsive if set up correctly. As I understand it the plates really don't move very much, 3/8-1/2", and with the stainless steel plates that are being put on newer v-drive boats using the pedal to move the plate and hold the plate can be physically challenging. Typically they are set up with a switch on the steering wheel so two hands on the wheel at all times.
I think the style is what best suits your set up and the room you have to work in. I got rid of mine and went with a foot pedal and lockout handle. For me, I always knew where the plates were set at. I've seen a lot of the electric ones though so the actuators must work pretty good
