I'd say Call of Duty is far more overrated than any of the listed choices.
As for the listed ones - all of them are bigger than God in some circles, all of them are worshipped for a good reason, and all of them tend to be at least somewhat overrated, so you could probably make a case for any of them.
Personally, I'll go with Halo, because for a PC gamer, the series is just plain average.
