I've never been one to trump up power and ko stats.

In the minority here but power can be misleading or blurred, at least percentages. You can put a V-8 in a Volkswagen Bug but if the driver doesnt have the skills its just a clown car. Ok...one metaphor too many

Punchers and power need the technique and delivery to get it home and matter otherwise punch for simplistic punch most are very similiar with respects to weight, ala Bailey. I think Matthysse is one of the truest hitters going also.
