I noticed you have an '08 so the answer isn't simple.
Most instructors will tell you to use the thumb switch first. There are two reasons for this. 1. It keeps the switch clean and working properly.
2. It becomes instinct, if you need to shut a bike off in an emergency.
Now for the '08 complication. If you accidentally rotate the throttle as you hit the kill switch it may reset the idle speed of your bike. (This was a little bug with the throttle by wire system, I think they corrected it in later years). Using the ignition switch reduces the possibility of this because you will probably remove you right hand from the throttle to reach for the ignition switch.
Now for the fix. If you find that your bike want to idle at much more than 1100 RPM it is easy to fix. Simply cycle the ignition switch on and off 4 or 5 times waiting a few seconds at each position without touching the throttle or starting the bike.

piasspj, there is a easy fix for the idle issue you describe, tt380 is a free download that solves this problem , also will give you the heat management system. dealer installed it for me and it solved that problem, took about 3 minutes.
According to the schematic for my 04, the kill switch takes power off of a pin on the security module and the main switch takes power off of that plus the lighting, fuel injectors, accessories, etc. Both the security module and the ECM remain powered regardless of which switch (or both) are chosen (how else would the alarm work?). I'd say it doesn't matter except for the issue of keeping the kill switch clean and habituation of hitting it first to kill the engine in an emergency. My $.02.
Kinda a strange post until the advent of ecm's and all. Just kill the motor and be done with it. Are they going to include this info in the MSF school?
