Each guide answers one hard freezer question honestly, using manufacturer specifications rather than invented ratings: chest vs. upright, whether you need a dedicated mini freezer at all, real dimensions by format, garage and outdoor temperature limits, safe defrosting, and what a freezer actually costs to run.
