Elite Square and Kickr v7? What is the "best" trainer and why?

No features in particular. I have a Kickr v5 right now, but that isn’t going to be able to do virtual shifting. I like the small bit of movement with the feet. Other than that, I don’t know that I have any desired features. Seems one of the things you get with higher end trainers is the ability to replicate steeping inclines beyond 16% or so. In practice, that isn’t a big deal though.
