There's really no benefit of using either one as a preference for the initial purchase because you can get the same thing at both (with the exception of Apple Care +, as spencerdl pointed out, but that can be easily added over the phone)...personally, I always go to the Apple store because it's convenient to me and I don't particularly like the attitudes at carrier stores (since they like to offer their "opinions" on the products I'M buying...lol). The crowds can certainly turn someone off from the Apple store, but when I'm actually buying something, I've never had to wait more than 10-15min. for service (and our local stores are always completely packed and chaotic).
