How we compare these two
Every figure here is pulled from the WordPress.org plugin API every day at 03:00 UTC, for both plugins in the same run, so the two are always read on the same day. We compare only what the directory reports: active installs, the rating and how many reviews stand behind it, the last release date and, once we have a month of history, downloads over the last 30 days. Ratings are only called a win above 50 reviews each, because a handful of five-star reviews is not evidence. Nothing is weighted into an overall score, no measure is worth more than another, and neither Advanced Custom Fields nor Flexible Checkout Fields can pay to appear here: the pair exists only because both plugins reached the Custom Field Plugins top 10.
