Oshino Shinobu rocketed to the top of my favourite character list as soon as she opened her mouth in Nisemonogatari. Her silky drawl is fabulous. Her laugh, even moreso. There's nothing I dislike about her. Nothing at all.
So while I prefer Shinobu: Total Badass rather than Shinobu: Cuddly Vampire, any form of Shinobu is good. That's just how she rolls. After all, you can't go wrong with Shinobu, and you can't go wrong with GSC. The only logical outcome is win.
