TLDNR:
The overall winner in Firefox is simply the quickest, and that was µBlock origin. µ AdBlock is a fair choice if you want an easy to use but fast blocker, the rest are almost identical so it’s down to personal preference and the options available as to which one you use.

The winner in Chrome is a closer call when you consider the results from all three tests. But as it got a couple of firsts and a second, we would say µBlock Origin is the definite winner, it truly is fast and efficient as the author claims. Both Ghostery and Adguard are still excellent choices and are viable alternatives to µBlock Origin providing good performance in all 3 categories.
