Verizon v. T-mobile and vice-versa

[gokart-mozart]

Verizon costs too much but it's been the only service that meets all my needs (live in Wolfeboro, commute to Concord or Laconia on 28, 140, 129, 11 and 11A).

Has anyone using those routes regularly switched from Verizon to T-Mobile, or from T-mobile to Verizon, that can comment on coverage, etc?

For now, I'm stuck with ABB/Breezline for high speed internet at home, and that doesn't look like their will be a choice for quite a while.
