Verizon gets the very top score in voice connection and quality and AT&T gets the lowest however some still try to argue that AT&T's GSM network is somehow superior to Verizon's CDMA network.
I think peoples standards are way too low if they think Verizon is great
But AT&Ts network IS vastly superior, in that it lets me use the Internet AND talk at the same time. I use that constantly, and sometimes really need it. I could NOT do without that, whatever AT&Ts other issues may be. (Such as, for instance, hair-rasingly bad customer service/support, where everyone you talk to has different info and the Truth is Not Out There.)
