This has been the question of the year for a long time.
Use the grinder you get the best cup from, the taste you want, the cup that makes you a great-cup-o-coffee and forget the coffee freaks.
I use a mini mazzer, I drink 97% espresso, I cannot get the grind I want from a burr grinder.
My neighbor uses a burr grinder with my roasted beans. She thinks my beans are the best but hated when I ground them for her; I gave her a burr grinder to use for a few weeks and she returned after a few days
She asked one day if I could just give her the beans and "not to bother" grinding. We had a conversation about the fact that she liked her "grind" from her "grinder" better.
Confusion is not limited to we older folk.
