I am not sure that I would go along with your line of thinking that in this case MMA and Krav are "inferior" to Aikido? Whilst both may be modern, so is Aikido by comparison, Krav also shares liniage with Aikido in its formation. I am pretty sure I can dial up any you tube video of someone using one martial art to overcome another, - it proves nothing however. The only person you need to compete with is yourself.
