Caching in WordPress, Voice theme

In my Performance Report, How to Improve section it says, “Install and configure a full page caching plugin like WP Super Cache or Batcache. “

However I have already enabled browser caching in WP Hummingbird.

Should I enable both WP Super Cache and browser caching in WP Hummingbird or just one of them? If just one, which one will be best?
