Whichever one you like and shoot the best. Both will kill elk & antelope. 7mm-08 and that 6.5 creedmore round will work too - less recoil...
To argue over an inch or two of trajectory is useless - do a dope sheet and use that or get a good scope with dial turrets for your ammo of choice - use same ammo for elk & antelope.
I shot 2 antelope this year - 25 (yes, archery range) and 340 yards. Had 4 other shot opps in the 175-200 bracket. Used dead hold range and then dope sheet for drop. 30-06 150-gr 2900 fps - zeroed at 250, dead hold to 325, held a little up at 340 and drilled it.
