Which KILZ is better?

Which KILZ is better? Which Kilz is better depends on job. KILZ Original oil-based is better for severe stains and odors like smoke, fire, water damage, pet urine, and nicotine, with strongest stain and odor blocking, good for interior and exterior, but high odor, needs mineral spirits cleanup, and high VOC. KILZ 2 All-Purpose water-based is better for everyday general priming, low odor, easy soap and water cleanup, good for drywall, wood, masonry, and light to medium stains, suitable for most homeowners. KILZ 3 Premium is better than KILZ 2 for better coverage, thicker, more stain blocking while still water-based low odor. KILZ Restoration is better for heavy-duty odor and stain, water-based but with shellac-like performance, low odor alternative to oil. KILZ PVA is better and cheaper for new drywall only. KILZ Mold and Mildew is better for mold-prone areas as it kills and prevents mold. So no single best, Original for worst stains, KILZ 2 for general low odor, KILZ 3 for premium water-based, Restoration for maximum water-based blocking. Choose based on stain severity, surface, odor, and cleanup preference.
