The Niche Zero is an endgame single-dose electric: 63mm conical burrs, stepless adjustment, and a 100 RPM motor producing near-zero retention and room-temperature grounds that preserve aromatics, with genuine espresso-to-French-press range. The C3 ESP is a manual grinder with a 38mm S2C burr at ~23 microns per click that reaches espresso for about $72, in a portable all-metal body, but grinds a double in 40-50 seconds.
Grind quality, retention, and convenience overwhelmingly favor the Niche — cleaner, cooler, more uniform grounds, essentially zero waste, and push-button operation versus hand-cranking. It's a perennial top recommendation. The C3 ESP's burr is good for its price but can't match 63mm conical burrs, and its dialing is coarse.
Price and portability favor the C3 ESP — under $90 and pocketable, versus a $629 countertop grinder with no Amazon availability. For an enthusiast wanting the best all-round grind and zero waste, the Niche; for budget, travel, or a first espresso grinder, the C3 ESP.
Buy the Niche Zero ($629) for endgame grind quality, near-zero retention, and convenience. Buy the Timemore C3 ESP ($72) for espresso on a budget or on the go.
