So Many Factors
I think there's a lot to be said for range of replies that have been posted to this poll. Some have commented about the phone, some about the service, and some about the customer service. As a small business with 10 iPhones and 8 iPads, we have a lot of experience with the network, hardware, and customer service.
In my opinion, the network could use some help up here in the Northeast. While the service has improved incrementally over time, we still experience what I consider to be an unnecessary number of dropped calls and a fairly regular inability to make outgoing calls. It's bad enough that all our employees have downloaded AT&T's "Mark The Spot" app to help identify problem areas. I can say, however, that I also have a standard Verizon cell phone and rarely have reception issues. I'll give AT&T Service a C+
The hardware? Well, I said it before, we all have iPhones and iPads, so that speaks for itself. We're in a 24-hour emergency response business, so we rely on having the best equipment that fits our needs. Apple gets an A- (The - comes from the fact that my Business Associate at the Apple Store forgot to place my order for a new iP4, making me wait an extra two weeks past when I should have received it
Being a business and having all these units, we interact with AT&T pretty regularly. They've always professional, helpful, and courteous. That hasn't exactly been my experience with the 17 year-olds at the Verizon store. We've had some billing issues with AT&T, but they've always done well to get it straightened out quickly and to our satisfaction. So, AT&T Customer Support gets a B+ (Would have been an A-, but they insist on sending us a detailed paper bill each month which looks like a small novel and is actually so voluminous, it needs to be sent parcel post in a small box)
