People who own v60s tend tie the promotion of v60s to their personal character so i know this might fall flat but; every real study ive seen, thats blind, has shown no no added benefit to slightly more consistent grounds. Ive noticed the same when testing between the two myself. Feel free to share otherwise if you have data to support that ;)
I don't doubt you but would like to read it and try to confirm my bias anyway!
My experience is mainly with completely crap grinders vs high-end burrs which is very distinguishable. Probably low/mid end burrs do okay as long as there aren't too many fines. Grind size variability may even be advantageous :)
The one i know of was done by Americas test kitchen. I had read and/or watched another a while back but couldn’t find it. Good luck with your cuppa - continue to enjoy the ritual.
Above the $200 range really only matter for espresso. Manual brews don't need that fine grind precision, just consistency (no fines, no rocks) at medium grind levels.
