Flat and conical burrs change the character
The DF54’s flat burrs tend to appeal to drinkers chasing separation and clarity, particularly as roasts get lighter. The Niche’s 63 mm conicals are loved for texture, sweetness and forgiving traditional espresso.
Those are tendencies, not laws. Alignment, coffee, water and recipe can overwhelm the burr-label shorthand. Still, your usual beans are a better decision tool than online claims about which geometry is more advanced.
The Niche premium is mostly about using it
The Niche’s large dial, straight-through path, tidy grind cup and quiet domestic design make it feel like a finished appliance. It is easy to understand, easy to clean and backed directly by a UK company.
The DF54 is more functional. The bellows, plasma generator and catch cup get the job done, but the ownership experience depends more on the retailer and on accepting a less refined industrial feel.
Our price verdict
The DF54 is the better recommendation for a first serious grinder because the saving is large enough to improve the rest of the setup. £320 can fund scales, a bottomless portafilter, water treatment and a lot of good coffee.
The Niche remains compelling when you already know you prefer fuller-bodied espresso and want the smoothest possible single-dose routine. It is a luxury of workflow, not a claim that £559 automatically tastes twice as good.
