Twinblade or dual curved swords?

[Quadsword]

I started my current build with the intent to use Eleonora's Poleblade as my main weapon (and the flamberge as a backup weapon against enemies like banished knights that laugh at multi-hit status weapons), but I lucked out with a pair of falchion drops early on and have been surprised at how good they feel to use.

Also, as much as I know the dragon communion seal would be a massive upgrade over the finger seal, I keep putting off going to get it because that dungeon is about as fun as taking an eye exam.

When enemy has annoying hyper-armor attacks/lots of poise, you'd want the twinblade. With certain Ashes of War, you'll be able to tackle any sized enemy without trouble. Curved Swords would be the more PvP-centric weapon of the two options, often taking advantage of human-sized players with its speed and dual-status buildup potential. I forget the AoW on Eleonara's Poleblade but either way, they're not too dissimilar.

Twinblade fully. While dual curved jumping and running attacks are quickest for setting statuses, I find the twinblade, and even dual twinblade movesets to be more interesting.
Even when not setting statuses, the twinblade movesets is still amazing

I like twinblades. I stopped at 60 arcane on this build. https://youtu.be/My7XwoD07QE
