I can update one device should I get iPhone 5 or iPad 4?

I can update one of my devices, I have an iPhone 4 and an iPad 3, I will use my iPhone a lot more than my iPad when I get my Mac I think so what do you guys think? Which is more worth it?

I'd go for the iPhone. The iPad 3 is so close to the iPad 4… Plus, they're starting to phase out OS features on the iPhone 4. You might as well get the latest.
