Title: ESC resistance

Do ESCs have lower resistance as the Amperage rating goes up?

In general they will, yes.  But it'll vary by manufacturer and model.  Older ones will probably have higher resistance than newer ones -- the progress in MOSFET technology in the past ten years has been absolutely astounding.  If you're a circuit designer, you can pretty much select a transistor for your circuit confident in the knowledge that by the time you get a prototype board back for testing, your spiffy new transistor's performance has been superseded by something smaller and with markedly better specifications.
