There would be a difference in my answer because in one scenario I'd be facing someone in an environment with rules who should know how to deal with submissions. The second situation would be NHB (no holds barred) and the opponent would probably be inexperienced in defending submissions.
Think of it this way, If you had to teach one person one submission, which would you teach them? The armbar is easy when at mount, but if you're stuck in the guard, you have to pass, then hope you have enough energy left to pull it off.
