Price Tier Matchups
IKO Marathon vs OC Supreme
Both solid 3-tab options. IKO Marathon includes algae-resistant granules standard; OC Supreme offers AR as an option. Comparable 25-year warranties.
IKO Cambridge vs OC Oakridge
IKO Cambridge now includes Class 3 impact (2025 update) — a significant edge over Oakridge at similar pricing. Cambridge wins this tier.
IKO Dynasty vs OC Duration
The flagship matchup. OC Duration's SureNail Technology vs IKO Dynasty's ArmourZone + Class 3 impact. Both excellent; choose impact (IKO) or wind tech (OC).
IKO Nordic vs OC Berkshire
Different goals entirely. Nordic is max impact protection (Class 4); Berkshire is luxury designer aesthetics. Choose by priority: protection vs curb appeal.
Storm protection priority: IKO's lineup offers built-in impact resistance at every tier — Cambridge (Class 3, $$) is hard to beat for value-minded homeowners who want hail protection.
Wind and aesthetics priority: OC's Duration ($$$) with SureNail Technology offers the strongest nail-grip performance and TruDefinition colors are unmatched in vibrancy.
Don't forget Atlas: If algae is your primary concern (it should be in Savannah's humidity), Atlas Pinnacle Pristine's lifetime algae warranty beats both IKO and OC.
