Flex Cache vs Jetpack Boost – Website Speed, Performance and Critical CSS
Both plugins as this registry currently observes them. Figures come from the same daily snapshot, so they are directly comparable, which two separate wordpress.org pages, read minutes apart, are not.

Install figures are rounded by WordPress.org to one significant digit, so a gap smaller than a band step is not a difference. Nothing here ranks the two plugins or recommends either, and no link on this page earns anything.
Why this page is not in search results
There are roughly 1.8 billion possible pairs of WordPress plugins. Generating them would be scaled content abuse, so this registry does not: a comparison renders for anyone who asks for it, and is offered to search engines only once 25 different people have asked for that same pair within 60 days. This one has been requested by 0. Until it crosses, the page works normally but stays out of the index.
