Grind quality: closer than the price suggests
In the cup both are genuinely excellent — blind, most couldn’t tell them apart. Both embarrass every electric under $250.
Adjustment: both excellent, K6 slightly finer
Both external numbered rings; 16 vs ~20 microns per click is a wash in practice.
Daily experience: where the $100 goes
K-Ultra smoother bearings, magnetic cup, better handle, more finished feel. K6 perfectly usable, slightly notchier. Daily-for-years → K-Ultra polish adds up.
The verdict
Buy the K6 if you want maximum quality per dollar — best value in espresso grinding, full stop. Buy the K-Ultra if the smoother daily experience is worth $100 — the “nicer object” pick. No wrong answer.
