What we actually measured
Every figure below is a reading from our own test runs, not a rating. Where a run never took a reading it says so.

Neither run recorded granules outside the box, ammonia after one day and ammonia after three days, so those rows are left out rather than filled in from a similar bag. The full test data shows every reading we have.
Why Naturally Fresh Walnut wins this matchup
Primary tradeoff: Naturally Fresh Walnut's weakest area here is tracking.
Strongest odor control in this set with strong natural absorption.
It still lands a stronger overall score than cheaper options because it is more balanced.
