Imo, the "best" are those who can step out of their look & be versatile; pose, taking all kinds of risks & being uninhibited; bring a certain magnetic energy their own personality & emote whatever feeling they are trying to project & make it believable.
You are describing Aymeline and Guinevere
I can't help but love them, partially because they are absolute editorial queens. Their work speaks for itself. I can lecture everyone about why that is but i'm sure everyone who's interested in both models already knows it.
And I do think it's a subjective matter, because from the models you mentioned there are also several I wouldn't consider great editorial talents either.
