This is only an issue for carbureted engines. For fuel injected engines, there is no risk of sucking extra gas into the combustion chamber when you kill the injectors.
I recommend a kill switch instead of cycling the ignition, mostly because all your computers - airbag, ABS, ECU, etc. power down when you turn the key.
Personally, I don't feel that P&G pays at high speeds, unless I'm headed downhill, but that's your call to make.
