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.
