Most comparison pages online are affiliate pages with the winner decided before the research started. These work differently. Every factual cell traces to the provider's own published page, each comparison carries the date it was checked, and where a straight comparison would mislead the cell is left empty with a note explaining why instead of being filled with a guess.
That also means these go stale. Pricing and plan structures move on the provider's schedule, so treat the verification date as part of the answer and check anything you are about to sign against the provider directly.
