Mechanically, it does seem that Edge, Agility, and Reaction are the more useful stats and thus the metatype that gives bonuses to those would be preferred. This doesn't stop my players from playing the less optimal races like dwarf and elf for their RP potential since there are ways to boost the good attributes anyway to keep up with the Jonses.

And I do like that about my players-- that they're willing to play suboptimal for the sake of RP.
