I would think the gravel geometry ought to be more stable than traditional CX geometry and as such traditional CX geometry is better on slower, twistier corners.

Regardless, it is most certainly possible to be competitive. Joris Nieuwenhuis raced the WC season last year on an Aspero. The biggest question, in my opinion, is whether shouldering a frame is important for your racing and if so, whether your gravel frame can easily be shouldered.

Next, beyond that is weight: I know my Cruxs are significantly lighter than my Aspero.
Third, I know my CX bikes are more compliant than the Aspero, but that will change based on Gravel model.

I believe that geometry will make a bike feel differently, however these geometry changes are so small that they will not have a major impact on lap times.
