All you did was restate "this is an equaliser and this is an equaliser" and you can't even explain how that is, let alone provide an argument on how your explanation is correct.
You didn't refrain from making a long argument, you don't have an argument at all.
Ok, I'll do this for you.
If it is wet and you have more power, this is a disadvantage unless you have a good medium for putting that power to the floor.
If a car has a good chassis and aero, it will have more grip, so in conditions where you need more grip, it would show.
Of course, we have the other area which is the software, which controls how the power is delivered.
But then again, watching the Red Bull in Suzuka, it wasn't all over the show, it didn't show lurid power on/off moments like you see with the Ferrari. However, when Hamilton set off after Rosberg, they left the RBR's trailing, by some distance, ditto Singapore. That's grip, that's chassis and aero, coupled with possibly good power delivery, or software.
The same, of course, is for smaller twister circuits where keep the car glued to the floor is more important that the extra 30 odd hp we're discussing.
And finally, one moment you are saying the red bull has the best aero, Merc the best engine, now it's power delivery? That's software, that's the engine maps.
So, in short, I think I am right and you wrong and no matter how many ad hominem you sneak in, you haven't given me anything in your argument which is strong enough to change mine.
PS - Massive power difference? Massive. And you know this how? Estimates vary from 30-50. Most sage's put it down to having a better ERS, not engine. But, I digress...
PPS - Just thought I'd add maybe we've seen some more of the dark arts of RBR being used, like the adjustable suspension, now flexi wings, just 5 years too late.
