WordPress Caching Plugin Rankings – Apr 2016 to DEC 2018

Across the 3 years of testing, both W3 Total Cache & WP Rocket have consistently been the best performing caching plugins.

When it comes to making a call on whether W3 Total Cache or WP Rocket is best for you, it usually comes down to compatibility with your site & host. Some hosts have banned plugin lists due to conflicts with their own caching solutions. If there are no conflicts, my suggestion would be to test both, 1 at a time, to see which helps speed up your site the most.
