As far as the number of reviews is concerned: uBlock Origin received more than 13200 reviews, thousands more than Adblock Plus' 8500 reviews at the time of writing. The average rating is 4.8 out of 5 on the Mozilla add-ons store, while Adblock Plus has a rating of 4.5 out of 5.

UBlock Origin beats Adblock Plus in other metrics as well. If the trend continues, the gap between the two ad blockers will widen in the coming months and years.
