KK is a semi-regular flavor of the week. Every year or two we get enough new members, they see one thread and are shocked that a dude with no powers and just skill is taking on metas heralds and junk. So they're like "no wai!" and start making threads to gauge his power. The recent incredulity in the Spidey v. KK thread is a perfect example.
Anyway, Val has the detect weakness thing going for him too. He's been able to look at, say, a large starship and find its weakness in moments. He also has better overall feats than karnak. So KK, solid majority.
