Espresso purists who single-dose and want stepless control for dialling in
Buy from the maker →This is the single-dose comparison people actually agonise over, and it is not really about price. Niche Zero and DF64 Gen 2 do the same job in the same workflow — weigh beans in, grind them all, nothing retained. What separates them is burr geometry, and that is a preference about the coffee you drink rather than a question of which is better made.

The short answer
Buy the DF64 Gen 2 if you drink modern lighter roasts, or you want to spend the difference on beans. Flat burrs are the geometry usually associated with clarity and separation, and DF64 Gen 2 is the cheaper way into that. Our record marks it best for budget-conscious enthusiasts who want flat-burr clarity and the option to upgrade to SSP burrs later.
Buy the Niche Zero if you drink traditional espresso and want the fuller-bodied profile conical burrs are associated with, in the quietest package here. Our record marks it best for espresso purists who single-dose and want stepless control for dialling in.
How we can say this: both grinders went through the same published evaluation against the same rubric, and each one's full record is on its review page. That is a repeatable, documented comparison; it is not a taste test, and we say so wherever it matters.

Which one should you buy?
Every row below is resolved from the two catalog records, not from a preference of ours; where the records tie, the row says so.
| If what matters most to you is… | Then | Because |
|---|---|---|
| Spending the least | DF64 Gen 2 | The difference is real money, and both grind espresso well enough that it could go on coffee instead. |
| Flat-burr clarity | DF64 Gen 2 | Flat geometry is the one usually associated with separation and clarity in the cup. |
| The smallest footprint | Niche Zero | Both are single-dose grinders that live on the counter, and the widths differ enough to notice. |
| The lightest to move | Niche Zero | One is substantially heavier than the other, which matters if it does not live out permanently. |
| Single-dosing | Either — the records tie | Both are built for it — weigh in, grind it all, nothing kept back. |
| Stepless micro-adjustment | Either — the records tie | Both adjust continuously rather than in clicks, which is what dialling espresso wants. |
| The quietest kitchen | Niche Zero | Manufacturer figures, and the gap between them is audible rather than marginal. |
| A longer warranty | Niche Zero | Worth weighing on a machine with a motor and burrs that wear. |

| Difference | $300 | |
The gap buys geometry, not build quality. Both are single-dose grinders aimed at the same buyer; neither is a compromise version of the other. If you have no strong view on conical versus flat, the honest advice is to take the cheaper one and put the difference into better coffee — which will change your cup more than the burrs will.
Conical vs flat, without the folklore
The claim you will read everywhere is that conical burrs give body and flat burrs give clarity. That is the conventional characterisation and it is roughly how both are described in our own records — but it is a tendency, not a law, and it is swamped by the coffee and the recipe.
What is documented rather than folklore: Niche Zero runs 63 mm conical burrs, DF64 Gen 2 runs 64 mm flat — sizes close enough to treat as equivalent, so the geometry is the difference and not the diameter. Both are stepless. Both are designed for single dosing, so in daily use the workflow is identical — weigh, grind, brew.
Our own record on Niche Zero states the trade-off in those terms: conical burrs are typically characterised as favouring body over clarity, and drinkers of modern lighter roasts often prefer what flat burrs give them. That is a preference difference rather than a defect, and we have not tasted either grinder to tell you which you will like.
The workflow is the same, which surprises people
Both grinders are single-dose: there is no hopper of beans sitting on top going stale. You weigh what you need, grind it, and the machine is empty again.
That matters more than the spec sheet suggests. Single dosing lets you switch coffees without purging, keeps beans in the bag where they stay fresher, and makes the grinder's retention figure a real concern rather than a footnote — which is why both of these are built to hold back as little as possible.
If you want a hopper you fill once a week, neither of these is the grinder you want, and our wider grinder guide covers that end of the field.

Buy on Amazon →Frequently asked questions
Is the Niche Zero worth the extra over the DF64?
Only if you want what conical burrs are associated with. Both are stepless single-dose grinders aimed at the same buyer, so the extra money buys geometry rather than build or capability. If you have no strong preference between conical and flat, the cheaper one plus better coffee will change your cup more than the burrs will.
Which is better for light roasts?
Flat burrs are conventionally associated with clarity and separation, which is what most people chasing modern light roasts say they want, and the DF64 is the flat-burr option here. That is the usual characterisation rather than a measurement — we have not tasted either grinder, and the coffee and recipe matter more than the geometry.
Do both grinders single-dose?
Yes. Neither keeps a hopper of beans on top: you weigh what you need, grind it, and the grinder empties. That lets you switch coffees without purging and keeps beans in the bag until you use them.
Is one quieter than the other?
The manufacturer noise figures differ, and the spec table on this page shows both. Those are the makers' own statements rather than our measurements — we have not put a meter to either.
Do either of these come with a warranty worth having?
Both carry a manufacturer warranty and the spec table lists each one. On a product with a motor and wearing burrs that is worth weighing, though neither figure is unusual for the category.
