The main differences center around storage capacity, form factor, and convenience. The TP-Link Archer AX21 provides extensive bulk storage capacity best suited for homes, garages, or basements needing deep freeze space. In contrast, the Arris SURFboard mAX Pro W31 offers a compact upright design that fits into smaller spaces with convenient shelf organization.
Chest-style freezers generally excel in thermal efficiency because cold air naturally settles at the bottom and does not escape when the lid is lifted. Compact upright models have lower total kilowatt-hour usage simply due to their smaller cubic volume, making both designs efficient for their respective intended purposes.

Measure your available floor clearance first. If you have open space in a garage, basement, or utility room and want to freeze items in bulk, choose the TP-Link Archer AX21. If you have limited room in a kitchen, apartment, dorm, or office and prefer easy eye-level access to items, choose the Arris SURFboard mAX Pro W31.
