Well, not sure if I have the answer for this one myself. But let's say that for whatever theoretical reason, it came down to ONLY these two brands, and you had to pick one or the other. No double spies; not choosing one or the other means... um... death? I guess? I know a lot of you will hate both brands, so you gotta choose the lesser of two evils.
I'm personally not sure which way I would go... maybe EA even though I dislike them they do have Bioware though
