That seems like a much better comparison. However, what it leaves out is the network usage. Maybe there aren't as many people using one carrier's towers in those other places or maybe the usage isn't as heavy. So while we know that AT&T's network can't handle the load we don't know if it's because of an inferior network or because of higher usage. I would be interested in seeing those kind of statistics compared for well performing and poorly performing networks, but I don't know if that information will ever be available.
