Agreed (and edited in the OP) on the Claw set.

Other interesting gear loadouts are possible, sure -- but trying to break down the numbers into a simple "rule of thumb" chart get complicated pretty fast, and is a bit more work than I'll likely tackle. In general, 4 points of STR = ~2.1%, and 2 points of damage = ~1.4% -- extrapolating from there is left as an exercise for the reader .
