I have owned Reynolds 531 frames that felt as if my input went into a black hole and did not propel me forward, and some that felt terrific.
Same with Columbus.
I have fewer Vitus 980 frames, and the three are fun. I do not really buy into the "planing" thing, but the flex is not a problem.
Of the three, I would place two as "artisan" one as semi production.

Good chance it is as much of the builder's effort than the tubing.
A wee bit on geometry and maybe a nod to how the chain stays are crimped or not. I prefer not.
