I would prefer the M1a for the simple reason of an assault rifle versus a battle rifle and the caliber you selected. The AR platform is a great assault platform with a quick reloading mag and very ergonomic design. Great for clearing a room or street.
The M1a is the last "battle rifle", still elegant in terms of its design, but the reloads take longer (mag exchange is a beotch until you get the hang of it). M1a is designed for longer range engagments, and is a direct decendent of the Garand, which gives it a classiness untouchable by the more modern ar-10.
The decision is ultimatly yours, but my money is with the m1a. Have I rambled on enough?
