Would anyone deny that MVdP is a "Legend" of the sport at this point? Or at least that he will be when all said and done? I have him as a legend, whatever that means in my brain. Would I call Vingegaard a legend? I wouldn't. 3 Tours, probably. All 3 GT's, probably, but not unequivocally. So likely both are legends when all is said and done. But for me, MVdP has the more impressive domination of his domain at this point.
I really like MVdP and I really like classics. I don't dislike Vingegaard, but his personality and riding style do little for me. So I have bias. But I also would say that MVdP has an objectively more attacking style, a more committed style, and has wins which made me stand up and shout out loud watching, while Vingo...not so much. MVdP in my view has a better palmares in his discipline, and has a style and panache which make him a legend. Where Vingo is a great rider, but not terribly inspiring.
