I prefer this over all.
Valen's Claws <---dagger- and Quietus -best dagger combo out there
Axe of the Unyielding +5 and Crom Faeyr -best head on combo in the game hands down, and my personal favorite
Infectious Scimitar and Water's Talon -poison them and give them disease for comulative damage
Celestial Fury and Sanchuudoku +4 -stun them, and lower their acid resistance, plus 2d4 more points worth of acid damage
Best weapons are those that can seriously hurt an opponent's status or can get in a lot of damage in a short amount of time.
That's my 2 cents...
