One-line verdict

For modern home baristas who want a quiet, low-retention grinder that handles both espresso and pour-over equally well, it outperforms older Baratza models on usability and finish but costs more than the basic OXO.

How it compares

vs OXO Brew Conical Burr ($100): Fellow Opus wins on retention, quietness, and espresso capability, OXO wins on price
vs Breville Smart Grinder Pro ($200): Fellow Opus wins on lower retention and modern design, Breville wins on built-in scale and dosing timer
