Which should you pick?
Honestly, in most of the places above only one of them will actually reach your building, and that settles it. Where both do reach you, the useful question is the technology rather than the brand.
Both are mainly fiber networks, so the technology argument does not separate them. Compare on price, contract terms and local service reputation instead, none of which the FCC publishes, and none of which we will invent.
