Calphalon ActiveSense vs Chefman Obliterator

The Chefman Obliterator and the Calphalon ActiveSense have different strengths, but the Chefman comes out ahead overall. The Chefman is better built, makes better nut butter, makes a smoother blend with small batches of leafy greens and other fibrous ingredients, and makes snow-like crushed ice with slightly less work from the user. It's also a bit quieter and easier to clean. By contrast, get the Calphalon if you primarily blend large batches of food; it has a larger capacity jar and does a better job dealing with big quantities of fibrous ingredients.
