ESC power delivery
 
I run in the silver can touring car class at my local track. We all throw our best stuff at our cars, but I am lately wondering what are the actual advantages of a high end ESC when running silver can. Motors, whether silver can, stock, 19T, etc. all have a limit at which they run. They will only draw so much current, with fewer turns translating to greater current draw and more power, etc. But to compare a silver can car's power delivery setup, say your basic Tamiya TEU speedo vs. a Novak GTX, don't they both deliver the same amount of electricity to the motor? The silver can current draw has a limit, well within the TEU's capacity, so what is the advantage of the GTX? Does it, CAN it deliver more current to the motor? Is it merely the programming?--many options, rarely used in my experience and observation. Drive frequency? More robust BEC?

Partly I ask because I recently blew my GTX and was running an old TEU while the GTX was being fixed (props to Novak btw--great customer service), and was rather surprised that after putting the GTX back in I didn't notice much difference. To be sure, I can tell myself that the nearly $200 speedo is clearly better than the $35 option, but that don't make it so. Care to educate?

Resistance is resistance. The High end ESC's will have less resistance at full throttle than the budget ESC's. The current in a circuit is dependent on all the resistance in that circuit, so reducing resistance anywhere will increase the current flow. To be sure, when talking silver can motors the actual difference may well be too small to notice, but that doe$n't $top u$, right?
