The 10% stat buff (179 attack and 54 HP) is probably going to be a lesser concern than having the right selection of active skills, in most cases. But it's true that in most encounters the attack down can miss, and in tough encounters you may be spending more than 3min per 9 rounds. Having two copies of this particular eidolon could be useful.
