I use the kill switch everytime I use the bike. I started on dirt and every metric street bike I ever owned up until my H-D had only a similar kill switch along with a keyed ignition. When I started riding the Harley, it was just second nature. In my mind the kill switch is the switch and the ignition switch is the "key."
I agree that there is no right or wrong. But, I do think the norm for long-time H-D guys is to leave the kill switch alone and just use the ignition switch.
