If by strength you mean duelling ability, then that + Bananji brains would be above HK tbh. Gaimou is far above Bananji in a duel obviously.
We only have a snapshot of his abilities though so it is a tough one. He was in about 10 chapters so plot dictated we had a limited view of his leadership skills or his tactics. He definitely had a good head on his shoulders though so would be far from a brute.
The stats will at least give us another layer of evidence to look at, given our limited knowledge at this stage.
