I’d agree with that (although sarda is piezo not est) for the most part, although I do think the sarda generally has a technical edge over the vxv outside of stage width and smoothness
So basically that’s one of the reasons why I think the crassi is a good pick because it gets real close to the technical ability of the sarda in some aspects while having a signature that would suit things a bit better in this case for an all rounder. Comfort about the same though
