The original Encore is a workhorse for pour-over and drip, with owners logging eight-year runs and easy repairs when parts finally wear out. The ESP variant chasing espresso grinds fine enough on paper but ships with a plastic burr holder that cracks predictably and an undersized rubber seal that lets grounds leak into the body, turning routine cleaning into archaeology. If you brew filter coffee and value long-term repairability, the original is a safe bet. If you need espresso, the ESP's fragile internals make it a gamble you'll likely lose within two years.
The Atom 75 is what happens when a commercial workhorse gets quietly adopted by home espresso obsessives who got tired of waiting. It grinds a 20-gram dose in eight seconds, runs whisper-quiet, and somehow keeps retention to 2.3 grams despite 75mm burrs, a combination that usually requires sacrificing a small appliance to the coffee gods. The height will not fit under every cabinet, and you'll want a dosing ring to catch the occasional escapee grounds, but those are the only real compromises. If you have the counter space and the budget, this is the grinder that makes you forget you ever cared about grinders.
