Best road helmet?

That’s nice of you! However, two remarks here. First, and more important, all helmets are differently shaped and that’s a very personal thing. If you don’t know which model or at least brand your BF fits best, it’ll be a gamble. Second, you selected two aero helmets. Is your BF riding fast and or competitive enough to need one? For most casuals, a more ventilated non-aero helmet is a better choice, e.g., Specialized Prevail 3 instead of Evade 3.
