Let's start some scenarios for those possibly looking at leaving Verizon because of the loss of unlimited data (not including the cost of the devices and any prorated first month charges).
Unlimited talk and text on 2 smartphones with 6GB of total data bandwidth -
AT&T Individual
Smartphone 1
Unlimited voice: $60
Unlimited text: $20
3GB of data: $30
Smartphone 2
Unlimited voice: $60
Unlimited text: $20
3GB of data: $30
Monthly bill excluding fees/taxes: $220
AT&T Family
Smartphone 1 and 2 unlimited voice: $120
Smartphone 1 and 2 unlimited text: $30
Smartphone 1 3GB of data: $30
Smartphone 2 3GB of data: $30
Monthly bill excluding fees/taxes: $210
Verizon Share Everything -
Smartphone 1 (unlimited voice/texts): $40
Smartphone 2 (unlimited voice/texts): $40
Shared 6GB of data: $80
Monthly bill excluding fees/taxes: $160
Closest way I found to get closer to $160 was to go with the AT&T Family plan with just 550 minutes.
AT&T Family
Smartphone 1 and 2 550 voice (with Rollover): $60
Smartphone 1 and 2 unlimited text: $30
Smartphone 1 3GB of data: $30
Smartphone 2 3GB of data: $30
Monthly bill excluding fees/taxes: $150
Conclusion on this example: you can make AT&T work for you if you stay at the 550 minute plan. Most here don't use voice so you can build up a nice cache of Rollover minutes just in case.
I purposely didn't go with the 300MB data plan at $20 since 300MB is probably dangerous for most to have. The 3GB plan at $30 just makes much more sense.
The Verizon Share Everything plan would work out if one line uses way more data then the other.
