[Rune Son of Bjarne]

If it is the armour on the picture we are talking about, then i would have to say that there is not much of a differens in the looks.

If we start talking materials used sure Boromirs armour is heavy and Faramirs is light.

But the best of the armour would be the one of Faramir, if they were to fight on their feet that is. Boromir's armour would be to heavy to fight with and he would get killed quit fast, plus it looks like he is allso wearing a chain mail! Have you ever tried one of those, they are quit heavy i can tell. Even for a mighty warrior. But if they were to fight on horseback Boromir would clearly have the advantage.

I am sorry if this is off topic,
