Brand Sets provide bonuses for equipping multiple pieces from the same brand (e.g., 3-piece Providence Defense for +15% Headshot Damage, +10% Critical Hit Chance, +15% Critical Hit Damage). Gear Sets (e.g., Striker's Battlegear, Foundry Bulwark) offer more specialized and powerful bonuses for equipping 2, 3, 4, or 6 pieces. Mixing and matching brand and gear sets is key to build optimization.
