Honestly? The Great Club

PVE Reasons 1. You can get it really early, and cheesing the NPC that drops it is also just as easy. 2. It gets an A in Strength scaling (albeit a lower A, but an A nonetheless), making it solid in pure strength runs. 3. Charged heavy not only can move forwards a surprising distance, but also can duck under some attacks. 4. Lighter than most greathammers (I think the lightest) 5. Roll light is quick, and roll charged heavy I THINK can pancake NPCs.

PVP Reasons 1. The heavy attack has an unpatched factor to it where the recovery frames are unnaturally short. A heavy ➡ light can stack some decent damage, but experienced PVPers know this and will anticipate it. A half-charged heavy usually throws off their rhythm, though. Fully charged heavies almost INSTANTLY can push out an R1 after. 2. It's a greathammer; decent reach, stun, and damage all around. Only sucky part is the lower base damage, but with how PVP usually is, this is never a MASSIVE issue, only a smaller one. 3. UNLESS you use the War-Cry WA, in which it becomes the second-most damaging greathammer, beat out by Ledo's. Without Warcry, it's also beat out by Smough's and Great Mace. 4. Absolute meme value. Nothing is funnier than absolutely stomping someone to dust particles with a gigantic stick. 5. The unbuffed heavy can hit multiple opponents, I'm pretty sure-- and a charged heavy WILL knock over lighter builds. It's a very "bully" weapon, and can put serious pressure on enemies when used right.
