Which sponge lasts longer without smelling bad — Scrub Daddy or Scotch-Brite?

The Scrub Daddy consistently outlasts the Scotch-Brite by a wide margin — up to eight weeks before it starts to smell or lose its structure. The Scotch-Brite’s abrasive layer flakes off after a couple of weeks, and its denser construction traps moisture, causing faster odor. The Scrub Daddy’s open-cell foam dries faster, keeping it fresh longer.
