As I fiddle with my back-up character (the last session came really close to a tpk) I have been investigating the differences between 2 handed and two weapon fighting.
Two Weapon Fighting
Pros: Looks cool. Good for many opponents with no DR and low AC. Exceeds damage of two handed style only at higher levels (14+). Many changes to land crit feats if you are using a high crit range weapon.
Cons: Requires a ton of feats to out perform 2-Handed. Requires both a high dex and high str to be effective. Lower chance to hit and low damage on each swing means DR is a problem. Only decent on a full attack.
Two Handed Fighting
Pros: Only need high str. Works best against 1 or 2 opponents. DR less of a problem. The Vital Strike feats make even attack standard actions good damage. Effective with few feats (Power Attack essential). Higher chance to hit for much bigger damage.
Cons: Large weapons cannot be used in a grapple/confined spaces. Fewer swings mean less chance to land critical hits.
