How fast the machine can mill the grain.
What the temperature of the flour is right after milling.
How easy the mill is to clean
How evenly the grain is milled and how fine/coarse it is.
Honestly, you can’t go wrong with either of the machines, but if you’re really after the smoothest, finest textured freshly milled flour, then the Komo wins.
In terms of wastage, the Mockmill gives you more flour for the same amount of grain compared to the Komo. I found that the Komo left some of the flour in the machine, which would only come out when I ground more grain.
