    How this page was made

    • The verdict at the top follows a fixed rule. When both tools are in the same category and either is in our top three for it, the verdict follows that ranking: the higher-placed tool is our pick. The top three weigh who each tool suits as well as its grades, so a pick can go against the GPA. Otherwise the page does not pick one and says which grades higher: the higher GPA first; on a tie, the one with a free plan, then the one that starts cheaper in dollars a month, counted the same way for both; if they are still level, what the choice depends on.
    • The grades are our own, from each tool’s review or report card. The GPA is their average.
    • Prices, plans and platforms come from each tool’s listing. The table above says where each price was read and when.
    • The differences and the answers to the questions are worked out from those listings.
