Both WP Super Cache and W3 Total Cache are highly-rated WordPress caching plugins. However, the choice between the two depends on your specific needs and preferences.
WP Super Cache is a free plugin with some basic and advanced caching features. But some settings require some technical knowledge, so we don’t recommend it if you are a complete beginner.
W3 Total Cache is a freemium plugin with a comprehensive set of caching settings. The abundance of features may intimidate beginners, but the ease of use is generally much better than WP Super Cache.
