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.
That is the case here: Quantum Fiber is mainly fiber and Spectrum is mainly cable. The practical difference is upload speed and consistency rather than headline download speed, we explain what that means here.
