At the end it is all about the whole package.
The best car is nice to have but it is still te driver who needs to find the for him best working setup. And that counts for all parts like tires, battery, ESC, motor and most important the driving skills of the driver.
And then you have fanboys.... The reason why "what is the best" questions will not give the perfect answer. That is why I love where the ETS has become today with one ESC/motor combo, an RPM limiter and handout tires determined by the organiser to make it as best as equal possible.
