Aaron throws the Galaxy S II brethren together for a dogfight battle!  AT&T's Samsung Galaxy S II is more like the international version and offers a dual-core 1.2 GHz Exynos processor, 4.3-inch Super AMOLED Plus display, 8-megapixel camera with 1080p HD video recording capabilities, a 1,650 mAh battery, and Android 2.3.4 (Gingerbread) with TouchWiz 4.0.  Sprint's Epic 4G Touch sports similar specs, but offers some nice improvements over the original, such as a 4.52-inch Super AMOLED Plus display, larger 1,800 mAh battery, and different design.  They're both available for $199.99.

It's hard to decide between brothers, but only one can win in a PhoneDog dogfight.  Will it be the Galaxy S II that resembles the international version, or the Epic 4G Touch with its giant display and larger-than-life battery?  We'll find out!  Part 2 of 2.
