I used Adblock Plus for a few years, and now I'm using uBlock since a month ago, but I can still see some ads (although they are relatively rare).
I have never used Adguard, but I've heard that it's good. But how good exactly compared to the previous two? I believe that there is a "premium version" which isn't free - I would not mind paying if it is truly better than Adblock Plus and uBlock.
Note that I have 16 GB of RAM, so RAM consumption is not a problem.
The "best" ad blocker is defined as:
- The ad blocker which can block the most ads.
- The ad blocker which can block ads as quickly as possible, without increasing too much the time it takes to load the pages.
- The ad blocker which doesn't cause problems like making Firefox crash (I'm not sure if any of them do cause Firefox to crash, but my Firefox crashes relatively often).
But item #1 is the most important: I want to see as few ads as possible.
