Best greatsword?

I'm doing a faith/strength build and I wanted to know what a good greatsword for it would be. I can't get hollowslayer bc i've already ingested the ballsack trees soul and i'm currently using Wolf Knights Greatsword. Also, if anyone has a better idea for a build (which i'm begging of someone to have because so far i've been switching between pyromancies and miracles) I'd love to hear it! (a dex/int build would be cool because of friedes great scythe but i have no idea how i'd go about that)
