As the title says, why do Hueys have 2 blades, while most others have 4, or the Sea Stallion has 6? And if you put 6 on a 4, does that mean more lift and better performance?

Fewer blades = cheaper and simpler to manufacture and maintain.
More blades = greater lifting capacity for the same rotor disc diameter.
More blades also have better sound characteristics, generally.
