I'm pretty sure that there's more to test than just pitch speed, my pimped Viper feels superior to my pimped Eagle when it comes to lateral thrust; I can handbrake turn my Viper into a docking port from the backside of a station. However, there's all this optimal mass business that needs factoring as well.
That's why you can find mass of the ships as well as the optimal thrust ratios in my second post and the calculations of the thrust per weight ratios as well. I did not perform these calculations for the smaller ships.
