I do believe VDP is in the end more talented, but for the classics.
However, Van Aert can run him closest in Roubaix, all it takes is a not super VDP and a Super Van Aert and Van Aert will beat him in Roubaix.
But a super VDP with form like today or glasgow sorry no, not even in Roubaix. However, take the VDP we had in flanders, who in my opinion was not super but just "very good", WVA would have a good chance with that form vdp in roubaix.
As for overall, Wout is more versatile and cerainly better suited to stages in GT's, TT's, mass sprints even... it's just that he wants to win the classics so bad where VDP just has the edge on him...you can't say they are on equal footing in those, you simply can't. VDP has now 6 monuments and a world championship... Van Aert 1. That difference is clear.
