you're splitting hairs between these two, they are running the two hottest calibers so bullet selection differences are moot, they run the same case, they run similar bc/sd, they mainly differ in bullet weight, even the front diameter difference is minimal, so it's like trying to pick fly sh@t out of pepper between these two...if you want another 150 yards effective range with a little longer mpbr over the grendel then get the arc and the expense of bullet weight and front area....lots of big game hunters will likely see that the extra 150 yards isn't necessary or worthwhile trade off for giving up that front area and heavier weight...as the grendel already holds good kill velocity to well past where almost any critter will get shot, if you're more predator calling, range plinking, p-doggin and the odd deer then the arc may be the better choice, but more big game work then the grendel is the better choice, that should cover it boys
