Side by side
Every provider with at least one currently usable free route, in alphabetical order so the table never rearranges itself between sweeps. That is a lookup order, not a judgement: there is no score, no total, and no winner, because whether a shared pool or a rate-limited cardless tier suits you depends on what you are building.
