Yeah, DkS1(R) can be alittle misleading when it comes to weapons but a general rule of thumb is; If it has decent Scaling and can be brought to +15 it will out damage nearly any weapon (in it's class) that can't be Buffed/Reinforced past +5. Most of all past NG+ when Caster/Melee builds run together. With just a few exceptions that Scale from 3 or more Stats. Like Greatsword of Artorias (Regular) that Scales effrctively with 4 stats and a Divine Modifier. This rule doesn't apply to Armor however as Black Iron Set +5 has the 2nd highest Physical resist and 1st Fire resist. Giants Set has the highest Physical resist at Max. Not Havels. Just a heads up, Drake Sword is useful for the first 4th-3rd of the game no matter your build. Easy to get, flat 200 damage.
