If you look on the items page, for (almost? I haven't checked all of them) every weapon, there are a bunch of crafted weapons, legendaries, and then at the very bottom of the list is one "white" item that has a higher damage than anything that came before it.

So if you find a rare of that white item, it will be better than any of the crafted items or legendary items with the same affixes.

I like it.
