You're really making a thread for a single item, which doesn't even involve working out a set bonus or trinket procc?
Higher Ilvl, duh. Shits directly = skill.
Find out how much of each stat the items give you, and then find out which is best. I'm fairly sure Shadowcraft does that anyway, but I don't use it often (not a Rogue).
Closing this since it's been answered. Cronight, if you've got questions about item comparisons that don't involve trinkets or set bonuses, the general answer is always going to be Shadowcraft - we can explain why if you link your profile, but please don't post open-ended questions, with no armory profile, comparing 2 items without qualification, after you've gotten an answer from Shadowcraft or SimC.
