I mean yes and no. The Tarmac SL8 is marginally better than the SL7 or any really aero road superbike but we have seen this for a better part of a decade where bikes have become so iterative and presented such marginal gains that anyone in the pro peleton could basically ride any bike and it wouldn't matter because at that point it's not marginal gains that are holding them back but really themselves. However once we translate these bikes for average everyday consumers or prosumers the advantages IMO are much more heavily felt because it starts trickling down to even entry level models. If Vingegaard is arguably the best rider in the world and rides a Cervelo S5 and ride it 1X than shouldn't everyone be riding this bike? The answer is no because not everyone has the legs or skillset of a pro and the S5 while an impressive bike it's also close to 18lbs even for a top of line Red AXS model and comfort wise it's far from cushy. Point being, while this bike is fine for Vingegaard, someone like OP probably has zero business riding a S5, it's just not optimal. So yeah there are grades of super road race aero bikes that are defiantly better for certain people and I guess I should note the Tarmac SL8 is the road race aero bike that the majority of people can ride comfortably, find a decent fit, and ride on a multitude of surfaces
