Does anyone have experience with Boost or MetroPCS or StraightTalk?

I’m considering changing to one of the monthly inclusive unlimited voice/text plans. Anyone have experience with Boost Mobile (Sprint), MetroPCS, or Straight Talk (TracFone)? Specifically, I’m looking for feedback on reliability (dropped calls), service area coverage (“Can you hear me now?”), ability to port over a current cell phone number from another provider, and customer service. I would need reliable coverage in NY, NJ, CT, PA, & NC. Thank you!
