Which cursed blade should I get after Raven Coves quest?

[Tiberius Fireskull]

Nautilus. I took Bitter End on my main pirate, and I used it for the first few weeks. After that? Nothing. It got boring, and it isn't that powerful. I took Nautilus on my other pirate and I use it a lot. It has critical strike, which is really helpful when looting bigger enemies. I'd take the Nautilus or the Spinecrest (simply because its a broadsword). Bitter End is cool... unfortunately, its not the strongest or best.
