How to read this
Everything above is measured, not opinion: commit counts and release dates come from the public repositories, and the health score ranks each project against all 1352 projects we track. Read the full method.
What this comparison deliberately does not do is tell you which has the better feature set. Maintenance health tells you which project will still be receiving security fixes in two years. Decide that first, then compare features on the projects that survive the filter.
