Shouldn't really be much debate on the international version vs at&t's model. Only thing you would loose is LTE. The international model is fully compatible with AT&T's HSPA+ network. No one seems to give that a thought anymore. Fact is - it performs the best it ever has. Very easy to achieve 9-10mbps down, which is more than efficient for anything.
