I'd compare it to parking a car. Robot A is my car in first gear, and Robot B is my car in 2nd/3rd gear, but I can only push the gas pedal half way down.
It would be harder to deal with the inertia of the car if it were stuck in second gear and had less torque. You'd try to move some small amount, but it wouldn't react until you applied lots of power, and once it started moving, it would be harder to stop.
I believe that the robot geared for 8 feet per second would be much more maneuverable and well suited for precise control, especially with skilled drivers. Lower gear ratio means more torque, and more torque means faster response. It's easier (to a certain point) if the robot responds faster. I don't believe 8 fps is too twitchy.
