Well props to you for getting it in the right place. TBH there is no telling without you specifying as alot of people dont post in the correct discussion, even people who have been around for 100x your whooping 22 post count. Hope that clears up my reasoning for asking? A little tip for posting questions on the forum.... Try to be as detailed as possible when asking your question, I personally wouldve hated to gear my answer "ASSUMING" you were rouge only to find out you posted in the wrong section.

As for the answer to your question you still never stated what you play style is so vauge questions get vauge answers.

In terms of over all stats I think that Flap jack is superior on several levels, however Esteban could come in handy for a lower armor rouge as it reduces 10% of all enemy damage output.
