Yup. I went from an aluminum Synapse to a SuperSix. I didn't even look at the CAAD10. Our roads are VERY rough chipseal (when they finally start to get smooth the powers that be have them freshly re-done, so then they absolutely suck for at least another 3 years...bastids!) and I had horrible road buzz issues with my Synapse. If we had mostly smooth asphalt I have a feeling I would have ended up on the CAAD, but men's with Rival. I never got the hang of Shimano's shifting.

Other than frame material, I believe all that sets that CAAD10 and SuperSix apart are material. The geometry is the same.
