Which one to pick
Each plugin is the better answer for the measure it actually leads on. Nothing here is a recommendation we invented.
LiteSpeed Cache
Pick LiteSpeed Cache if you go by where WordPress.org itself puts them, you want the plugin more sites already run, you want the score backed by more reviews or you want the one shipping releases most recently.
WP-Optimize
WP-Optimize does not lead on any measure we track, so pick it only for something these numbers cannot show, such as a feature you need.

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 LiteSpeed Cache nor WP-Optimize can pay to appear here: the pair exists only because both plugins reached the Caching Plugins top 10. Full methodology.
