Any fun build/weapon after morgott?

I just killed Morgott and advanced to kill the ice dragon. The thing is, this is my first playthrough, and I started with a strength build using Guts' sword. Later, I switched to faith and strength and tried Ordovis' Greatsword, the Gargoyle's Blackblade, and the Blasphemous Blade, but they all bored me since they basically have the same moveset. Now I tried leveling up the Giant Crusher to +20, and it disappointed me a lot—I really don’t like the R2. Now I'm wondering if there’s a good and fun weapon for this point in the game, preferably a big strength weapon.

Disclaimer: I don’t think these are bad weapons; they just aren’t what I expected. I’ve played the other Souls games, and I’d like to try a weapon with fun mechanics to really explore the game’s potential.
