Which weapon is better?

[J.T.]

Well, i'm going with Swashbucklers, last time I remember I used stun shot it didn't do to much on an invasion enemy, and i don't use blunderbuss much anymore anyway since I got my famed sabre.

I'd prefer Swashbucker, the healing boost helps emensly, still carry tonics, so you can face harder enemies and you have to wait less time between fighting enemies because you can easily heal and go. Sharp Shooter is also helpful to make every shot meaningful.
