My opinions? Well, FWIW, I've got a Top 5.
Best melee weapons statistically:
1. Crom Faeyr
2. Celestial Fury
3. Blackrazor
4. Vorpal
5. Soul Reaver & Holy Avenger
Best in terms of usability in the game:
1. Crom Faeyr
2. Celestial Fury
3. Vorpal
4. Warblade
5. Impaler
Notice I've left out Blackrazor, Carsomyr and Soul Reaver from my second list due to the usability restrictions in the game. I've also excluded staves like the Staff of the Magi and the Staff of Power as they are less "melee" weapons than wizardly aids. I've also excluded Drizzt's weapons.
Feel free to disagree - opinions are like a-holes - everyone's got one.
