Best FORCE weapon?

I made my build mostly around the force stat, getting the traits to get more force regeneration, traits to recover force etc, but I'm not sure which of the three force scalling weapons I should use, I've been using the curved glaive, but there's also the tooth fist and the pincer glaive, do any of you know which of the three is the best or have used them a lot/have good knowledge about them?
