Titania A slot

I have my Titania merge project here, she's +Atk -Res but it doesn't really matter for my question. Which is, I got a Katarina with bad IVs I would totally fodder off for Swift Sparrow, is it worth it to give it to my Titania instead of Fury? It would give her more offense and -somewhat- more bulk by not taking damage after combat, but those +3 stats in def and res do help her not getting one shot.
(Oh and by the way, ignore the Atk Smoke 1. I'm waiting for Atk Tactic fodder.)
