What Is The Best "Weapon Setup" Statistically?

Just curious if there is a statistically better/best fight type

What i mean is, the best combination of:
Weapon Proficiency, Weapon Style, Actual Weapon

This is assuming you can do everything.

Just in my head, i figure the best would be something like: War Hammer, Dual Wield, Runehammer +5 + Crom Faeyr

Is this the best possible setup statistically? Just curious if there is technically any better :D.

Thought it would be an interesting discussion.

Furthermore, what is the best setup for each weapon proficiency.

IE: Dual Wield, Angurvadal +5 and Blackrazor (Long Swords) etc, etc

And is there a weapon proficiency that you think actually works better when it is NOT dual wield (other than two handed weapons obviously)? where Sword + Shield may be better?

The most powerful setup i have done was:

Half-Orc Berserker
Strength: 25
Dexterity: 20 (i think) i think i had 18 original, read the tome, 19, equipped shruppak plate, 20.
Constitution: (not that it really matters) 20

Grand Mastery in Flails and War Hammers
Mastery in "Two Weapon Style"
Primary Weapon: Flail of Ages +5
Off-Hand Weapon: Crom Faeyr

EDIT:

Re-clarification of question as requested:::

There's stuff missing in your question; the kits and other equipments than weapons. To really know the best 'weapon' setup, you need to consider the classes and races and equipments and such, even abilities.

I haven't been through TOB enough to remember all the exact weapons/items names used, but favorite combos for devastation always were an Elf Kensaï on Kaï and stuff with Long Sword/Katana, and Half-Orcs of various classes using Flail/War Hammer. Always Haste/Bless/Chant before big brawls of course.

I know that doesn't answer the 'statistically' part of your question either, so I'll just tell you; go with the Elven Kensaï and pick between Long Swords/Katana/Scimitars. It's better to grow only one at first along 2 weapon fighting, then add a second one once 2 weapon is fully masterized.

The question is assuming best case scenario for everything...Meaning an acceptable response would be:

Spiders Bane + Short Sword is the best combo for Druid - two short sword +2 is best for blackguard paladin, however : Two short sword +2 with a blackguard is more effective than spiders bane + short sword for the druid, therefore, Two Short Sword +2 with blackguard is the best overall weapon setup in the game...

Obviously those weapons are complete BS, but hopefully that makes sense...You can assume that you have max everything (if possible). IE; you can assume that dexterity is allowed to be at 21 due to being an elf, reading the tome, and having shruppak plate, etc. Or at least give that info in the answer.

I want to know the best overall weapon setup for any class/setup that beats any other overall setup...Hopefully thats more clear.

Essentially, as long as the setup is possible in game, its possible in this question scenario.
