One thing that seems consitent with Verizon is excellent customer service. I recently switched my service to them, in party because the staff was so helpful and friendly, even gave me a discount on a phone which was about to go on sale the next day.
The coverage in the city seems excellent, and if you want to pay a little more, you have access to a whole world of entertainment - songs and games to download, etc.
One downside - phones run on CDMA, no SIM card, so you can't take them overseas, but if you use your phone mostly locally, this won't cause you any problem.
