I'm a defensive player most of the time, so a two-handed weapon doesn't hold a lot of appeal to me. However, during a regular fight the BS does do more damage than the Master Sword. However, not all two-handed weapons do more damage. For example, the hammer in OOT does not do as much damage as the MS by a long shot, but you can use it to stun effectively and to "cheese" difficult enemies. It'll take longer, but sometimes can lead to less damage taken. In OOT I rarely bother to get the BS because it is a two-handed sword. However, I ALWAYS get the gilded sword in MM. I just use a time-line to get the razor sword and instead of taking the razor sword to rights I just immediately go for the gilded sword. I honestly don't think "wear and tear" has anything to do with the Master Sword, as it is a blade of destiny, kept in the sacred realm, so the whole rust and chipped thing doesn't factor in at all. The Master Sword is just as awesome as it always was (except for maybe when you need to collect force gems), but hack-and-slash play styles would have some people gravitate toward alternative blades.
