Our verdict
1-2-3 is the affordable, widely stocked all-rounder for drywall, wood, and exterior prep. Smart Prime costs more but blocks stains closer to an oil primer and bonds to tougher substrates like tile and metal while staying low-odor. For everyday priming, 1-2-3 is enough; step up to Smart Prime when you need stronger stain blocking or grip on slick surfaces without oil-primer fumes.
