It depends on your priorities. Duration has the stronger nailing technology (SureNail) and base wind warranty (130 mph). Landmark has the wider color palette (24 vs 19) and slightly cheaper material cost. For most homeowners, contractor certification matters more than the shingle brand.
Both are roughly 230 pounds per square. The weight is essentially a tie. If you want significantly heavier, look at Landmark Pro (270 lbs/sq) or designer lines like Belmont or Grand Manor.
CertainTeed Landmark is about $5 per square cheaper at retail. On a 30-square home, that is $150 in material cost — generally invisible at the total project level. Both run $450 to $600 per square installed.
SureNail is Owens Corning's triple-layer nailing strip that creates a 600 percent wider nailing zone, helping installers hit the right area consistently. Quadrabond is CertainTeed's four-part sealant system that improves shingle-to-shingle adhesion. Different approaches to the same goal: wind resistance through stronger fastening.
Both are lifetime limited material warranty with 25-year algae protection at the base product. The warranty length on paper is essentially identical. What matters more is the workmanship warranty tier offered by your contractor (OC Platinum Preferred or CertainTeed SELECT ShingleMaster).
Either works. For hurricane zones specifically, Duration's SureNail nailing system has a slight edge for installer-friendliness, but CertainTeed Landmark with proper six-nail upgrade reaches the same 130 mph rating. Florida insurers do not prefer one brand over the other.
