I use Arm & Hammer HardBall cat litter, and wow, the clumps are solid. Scooping is super clean, almost no breakage. Odor control is strong, but the scent is noticeable at first. My cats didn’t mind, thankfully. Tracking is average. With Kirkland Signature dry food, the litter really locks things in. It’s not the cheapest option, but if clump strength is your priority, this one delivers.
