The DF64 Gen 2 is a single-dose espresso-and-filter grinder with 64mm flat burrs that match grinders costing 2-3x more, plus an open platform for SSP and other aftermarket burrs — near-unlimited upgrade potential. 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 travel-friendly all-metal body, but grinds a double in 40-50 seconds with a 25g chamber.
Grind quality and electric convenience favor the DF64 — larger flat burrs, cleaner and more uniform grounds, and push-button operation (with a ~$20 bellows recommended for puck prep). Its stepless adjustment has no numbered positions, so keep a log. The C3 ESP's S2C burr is good for its class but can't match 64mm flats, and its dialing is coarse.
Price and portability favor the C3 ESP — under $90 and pocketable, versus a $399 countertop platform. For an espresso-focused buyer wanting quality and upgrades, the DF64; for budget, travel, or a first espresso grinder, the C3 ESP.
Buy the DF64 Gen 2 ($399) for near-professional grind quality and an upgradeable platform. Buy the Timemore C3 ESP ($72) for espresso on a budget or on the go.
