If you want theory craft, then I can give you that. No one can say for sure as we haven't tested these mechanics yet, but we can get a good idea based on how stuff is likely to play out.
I would say Janoa, and Brudvir are the foremost Fighting types. Hrothi and Neran close on their heels.
Janoa have the advantage of strength, but the disadvantage of pride. A pride that has gotten them wearing tigers on their heads instead of steel.
Brudvir have an advantage of strength as well as they hunt to survive. If they don't catch the dryas elk out there in the taiga then their village starves because frankly their environment is pretty inhospitable.
The Neran and Hrothi both have maybe lesser strength, but the Neran are adaptable and the Hrothi are sturdy. And both of them have higher technological advances as far as war-faring with better arms and armor, and more advanced steel.
The Dras and Kypiqs I see fighting more intelligently, so if we are talking a duel in an arena, definite disadvantage. If we are talking war, I would take the clever side over the brawny side any day. What good is steel when you are dead before you see your enemies.
The To'resk... Meh. I know nothing about any combat capabilities they might have, but I get the impression they are more barter and less bite.
TLDR: When it comes to war, I say balanced. When it comes to an arena fight, or a duel, Janoa have a good advantage.
