If you're not worried about competition of exotics in your other slots, Truth is a very solid launcher. Might not deal the extra damage of the Hezen or Gjallarhorn, but it's useful for those pesky void shields.

I have then both and am very happy to have them both. Truth is disgustingly satisfying in crucible, it's always my heavy. Definitely get it. It can easily blow up in your face in PvE though, proximity is dangerous.
