I've owned carbon forks on a few different bikes now (Specialized, Easton, Lynskey, etc.) and have ridden countless others (Trek, Giant, Felt, etc.) and I couldn't really tell a difference in the various carbon forks. They all felt essentially the same to me.

I recently got an Enve 2.0 and it feels "better" to me than the others did. It still has plenty of stiffness in handling, but just a lot smoother feeling on the road than the others I've ridden. Less road chatter as well. I'm happy I went with Enve and will likely do so again in the future if I need another one.
