Niche Zero vs Df64 Gen 2

The Niche Zero uses 63mm conical burrs that produce a fuller body, more sweetness, and a traditional espresso profile. The DF64 Gen 2 uses 64mm flat burrs for brighter, clearer flavors with more separation between tasting notes—ideal for light roasts and single-origins. Your preference depends on your coffee: if you drink mostly medium-dark roasts and want classic espresso, choose the Niche. If you prefer light roasts and want to taste every nuance, the DF64 wins.

The Niche Zero has a more refined, premium feel—the metal construction, smooth adjustment dial, and overall fit-and-finish are superior. The DF64 Gen 2 has improved over the original but still has some plastic parts and a less polished feel. Both are reliable; the Niche feels like a $650 product, while the DF64 feels like a $400 product that punches above its price. For pure build quality and aesthetics, the Niche wins.

Yes—the DF64's ability to swap in SSP burrs (High Uniformity, Unimodal, etc.) lets you customize your flavor profile without buying a new grinder. SSP burrs cost $150-200 and can transform the grinder. The Niche has no burr upgrade path. If you're the type who likes to tinker and might want different burr sets for different coffees, the DF64's flexibility is valuable. If you want a complete, no-upgrade-needed package, the Niche is ready out of the box.

The DF64 Gen 2 is more versatile—flat burrs excel at both espresso and filter, and the larger burr size produces better coarse grinds for pour-over. The Niche can do filter, but its conical burrs are optimized for espresso; filter results are good but not exceptional. If you want one grinder for everything, the DF64 has the edge. If you're 90% espresso, the Niche's workflow and espresso quality make it the better choice.
