It takes a couple of minutes to die, but a decapitated head is unconscious in less than ten seconds. And death from lack of oxygen doesn't hurt; the pain in suffocation is actually from having too much carbon dioxide in your blood, not from having too little oxygen (or too little blood).
Decapitation is more merciful than dying from a gunshot, unless the bullet itself destroys the brain.
