They will have a decent honeymoon period where they will still get enough disgruntled ATT iPhone customers switching over who are willing to ignore Verizon's own quirks for the time being. Eventually this will slow down, as Verizon's shortcomings begin to stem the defections from ATT and ATT will probably do a couple of things (improved service or stellar deals) that will maybe even draw some old customers back. ATT is still a better bet longterm, as they have complimentary services (they are a cable and internet provider), but there is also the danger that they will be loss focused than Verizon on finicky iPhone customers and will not be able to provide whatever Verizon rolls out to please them. This will be interesting going forth.
