PvE Strength Build

Hey guys, So I'm on my first play through right now, currently starting the Catacombs of Carthus, with a strength build. I use pyromancies a little bit, but I normally use a 100% physical shield and a raw claymore +4. I'm trying to stick to using swords only, so i was just wondering what are some really good swords (normal, great swords, or ultra great swords) for PvE? For reference, I just transposed the Wolf Knight Greatsword from the abyss watchers and also got the Dark Sword dropped from a Darkwraith.
