Glo Fiber vs Xfinity
These two overlap in 23 metro areas and 130 towns and cities, so for a lot of people this is a real choice rather than a hypothetical one. The first question is not which is better. It is which of them can reach you.

We do not publish speeds or prices here. Both providers change them constantly and by market, and a stale number is worse than no number. Coverage is the part that is federally reported and verifiable.
Where you can get both
Metro areas where both Glo Fiber and Xfinity report service, ranked by how well covered the less available of the two is because that is what decides whether you genuinely get a choice.
These percentages count each operator's whole reported network. 67.6% of what Glo Fiber files with the FCC is fiber. The FCC publishes that split nationally and never per metro, so a high number here means the operator reaches the metro, not that it reaches it on that technology.

Showing the eight best covered of each. Ranked by reported coverage within the metro, from the same FCC filing as the table above. Providers self report and overstate, so read these as a ceiling on where a company will sell to you, not a promise about your street.
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: Glo Fiber is mainly fiber and Xfinity is mainly cable. The practical difference is upload speed and consistency rather than headline download speed, we explain what that means here.
