What is stronger, pure strength greatsword or pure dark crypt blacksword?

[Thomas Devlin]

I decided it would be fun to try an ultra greatsword run and I hit kind of a block. I ran straight into no man's wharf and grabbed the greatsword for my first weapon, with the intent of maxing it out then working on a boss weapon as I went, I thought the crypt blacksword sounded fun, so once I unlocked it I specked into that, got the dark infusion and used dark weapon to buff it even further, but looking at the AR on fextralife it looks like the greatsword might still perform better just with a stock weapon buff like gold pine resin.
I intended to use the greatsword until I found something better, but so far it looks like the greatsword is just the best weapon I can use, I haven't gone too deep into the scaling of the buffs since that goes beyond basic spreadsheets so the crypt blacksowrd might end up stronger if I keep working towards it, but at the moment I can't tell because nothing is optimal yet. If the greatsword is just objectively stronger then I might just start using other strength weapons instead, one powerhouse weapon for the entire playthrough is already getting kinda boring

That's actually a good question, but wouldn't KUGS be better for more of a str build?

Obviously, the benefit of crypt blacksword is a larger moveset w/spells.

Alrighty.
At 99 str/int/faith (and 10 dex) dCBS has 301+539 AR
At 99 str/dex rGreatsword has 650 AR
At 99 str/dex rKUGS has 710 AR

This isn't including any other gear but the weapons and using deprived base stats.
You can add ~30% AR with Dark Weapon or equivalent buff.

Btw, if you don't want to level so much:
At 40 str (and 10 dex) and 30 int/faith dCBS has 292+478 AR
At 99 str and 10 dex rGreatsword has 619 AR
At 99 str and 10 dex rKUGS has 686 AR

So, uh, ya, I'd go with (d)CBS unless you are vs something really resistant to dark. More AR and greater moveset w/spells. Well, to be fair, I already have =)

*Most UGS in PvP are about as useless as another, as it requires relying heavily on parries or backstabs to land a single hit. Can easily squish someone who doesn't know what they're doing, but that's about it.
