Since it's pretty much just a rule-of-thub, yes. If I had to guess I'd say aileron's would be faster than elevators (since ailerons are usually smaller surfaces, so less inerta and airloads) which in turn would be faster than the rudder (which is also the "least primary" of the three surfaces in many ways). But there might not be much between the surfaces (and other factors, such as design constraints for weight and space, might constrain actuator sizing in each case)
