Mac Help?

I need your inputs and suggetions!!

I start college in the fall and I will be getting a laptop.... but im stuck in the middle on which one i should get. I am between a specd out macbook air or a upgraded macbook pro 13 with Retina display(256GB,3.0GHz)?

Does the macbook air battery life out weight the retina display on the macbook pro?

Thanks in advance for your suggestions!
