Whether you do better as Unholy or 2H is largely going to be based on the encounter but seeing as your overall ilvl is 521 but your weapon is 536 (and you don't have fabled feather) I can virtually guarantee you'll be seeing better numbers as 2H frost.
Also, stat weights or not I'd still go for about 7K haste before bothering to put anything into crit or mastery.
