I don't know about good but I want to tell you about sprint I don't know how true this is for Others but for my family sprint sucks. They sent us our own tower that hooks up to our computer and we still don't have very good reception. We rarely receive texts and it doesn't make us happy. We Would switch companies but we are on a contract that we could get out of for free since we called in and complained so many times but we just got new phones and yeah I have heard good things about us cellular though
The best company for network service provider would probably have to be Verizon Wireless. As comparative to other service network providers. Such like At&t or Sprint, T-mobile. etc....However Sprint has excellent coverage as well, making them also as good as Verizon.
