The lowest resistance stator will win with all other things being equal! Equal means both motors tuned to the max for the class with car and driving being the same for both motors. Rotors are tuning tools, normally you would want the highest magnetic strength rotor you can get for Blinky type racing. Stronger the rotor, faster the motor gets back to top rpm. Of course a very wide open track you will be able to use a lower strength rotor due to never getting off the throttle.
Lower the resistance of the stator the more RPM the motor will have! A motor that is .3ohms lower than another motor can be as much as 300rpm more under load! Even a 100 rpm is a bunch in a brushless motor!
But, most of us includes me will not see the difference is a couple of points in a ohm reading. Why you ask, because if you can't run perfect laps every lap the benefit of a better motor will be lost in the first crash!!!! So pick your favorite motor and go have fun!
One brand of motor may not be perfect for every track, this is why they allow us to practice!
