Let me reiterate as you did not address anything from my comment: But how is it all relevant to the discussion? Bottom line is that using adblock in one browser and not using it in other browser makes the comparisons meaningless...

Adblock is a browser feature just as much as GPU acceleration.

Suggesting you need to add third party GPU acceleration to make things fair is ridiculous. But, you seem to think Adblock is somehow different.

No, I can make things fair by doing another test. Let's test Opera with adblock and Edge without, but only use websites that do not have ads. Sounds good?

Problem with Opera's comparison is that it is not fair because they don't display the same content - they (probably) need to render less. Of course they will be better if they render less (unless they are really bad at what they do). So to make the comparison meaningful, make them display exacly the same thing - then we can talk about who is more power-efficient.
