The Weapon Specialization argument is nice, but I think I would rather use Power Attack. Since the two-handed weapon guy doesn't suffer a -2 penalty to hit, he can choose to Power Attack for 2, gaining the benefit of the two-weapon fighter without spending two feats.
Power Attack is not the same as WS. Let's put in Power Attack for the Greatsword user. From my previous post, with a 2 point power attack added in:
Greatsword: 2 attacks
1 2d6 +1.5Str +en +WS +2 (+9)
2 2d6 +1.5Str +en +WS +2 (+4)
TWF: 4 attacks
1 1d6 +Str +en +WS (+9)
2 1d6 +Str +en +WS (+4)
4 1d6 +.5Str +en +WS (+9)
5 1d6 +.5Str +en +WS (+4)
Assuming that all attacks hit (which is a big assumption, I know), then:
Greatsword = 14 +3Str +2en +4 +4
2SSwords = 14 + 3Str +4en +8
(en = +3 for an 11th level GMW)
Greatsword = 28 +3Str
2SSwords = 34 +3Str
.
.
.
These are still not the final numbers. The greatsword user tends to have a higher Str (by 4 points or so), an extra special ability on the weapon (due to having only one weapon to enchant) and the 3rd attack will do more damage overall. However, this is offset by the fact that the shortsword user crits almost twice as often (due to more attacks) and thus their WS/enhancement bonuses become even more crucial.
Conclusion: Unless you're a rogue, or have an elemental (burst) weapon, you're better off with the greatsword.
Elemental weapons for TWF are a really bad idea (barring GMW). The main problem with TWF is the fact that you don't hit as often. If you don't have a GMW buddy, then a straight enhancement bonus is way better. Also, elemental attacks are worthless at higher levels, especially when everything under the sun has ER.
[A better special ability is the "Impact" ability from the PsiHB. A straight +2 bonus damage that multiplies in a critical. My favorite TWF weapons are keen, impact, and charged.]
IMO, however, I would rather go blade-n-board.
Style? Or because you feel they are more powerful? Just curious...
