Which Carrier is better? Page Plus or Ting?

I just started with ting and the service sucks. I'm going to buy an iPhone, and not sure whether to switch to Pageplus and get better service (through Verizon's network).Ting is through Sprint's network, and it is not prepaid. It is also a bit more expensive. I know the obvious answer is Page Plus, but does anyone have experience with either or both of these services.

Also, does Page Plus allow you to bring old iPhone or iPhone 4s from verizon?

Reception will always depend on where you are - have you checked the coverage maps for the companies? Also Ting has free voice roaming on Verizon so you might have similar reception with Page Plus.
