Speaking personally, I would say it all comes down to your own characters perception of each individual race and clan. My Hyur, for example, would probably not worry too much about picking a fight with a Lalafell because of their appearance, even if they were more powerful. My miqo'te, on the other hand, would be cautious in battle with any of the races. OOCly, my general rule of thumb is, "If they can do it in-game, they can do it with the best of 'em in character". Hopefully that makes sense...hahaha.
