Mechanics/Stats on proc chances for weapon enchant

[Zarathustra]

In the opinion of other Lurkers, which is the better enchant overall: Crusader or Lifestealing?

I had that discussion with a friend the other day. He's saying Crusader would be better for his 2H Axe Warrior (who may be going weapon/shield very soon), and I'm thinking Lifestealing due to the number of procs and the added damage.
