TWF versus Multiattack

[Mockingbird]

Which is a better feat for natural attacking, Two-Weapon Fighting or Multiattack?
On the one hand, Multiattack reduces both your penalties more. On the other hand, TWF lets you take Improved Two-Weapon Fighting, which gives you more attacks.

[SamBurke]

Do not go down the road of TWF. There lies madness.

Multiple attacks vs Better hit chance depends on your damage. If you're dealing low damage, do TWF, and expect DR to screw you seriously. If you're dealing good damage (PA/High Strength bonus, etc), then go Multiattack for more chance to hit.

[Godskook]

TWF gives no benefit when attacking with natural weapons, with the 'special' case of unarmed strikes, but those gain no benefit from Multiattack.

Could you be more specific as to how you want them compared?

Use Multiattack if you have natural attacks, TWF if you have manufactured weapons.
