i know the first 2 give more mastery, but with those i am having to gem for spirit+crit. with the 2nd half i would have a bit more crit and would be able to gem pure int+crit gems. which 2 items would be better? thanks

Well, I would assume as HC WF Darkfang is bis, that the heroic version + the teir legs would be better.
That being said have you had a look at wrathcalcs to see which gives more deeps?

You should use wrathcalcs so you don't get in the habit of asking which item is better every time you get a piece of loot
