iPhone 5 vs 4s .... Question ?

Those of you that had or have an 4s and have a iPhone5 .... can you see a difference in camera performance. Not on the iPhone 5 screen which is better but in a printed or downloaded picture to a iPad or ?

From the info I have read, the cameras are very, very close and the improved image quality maybe the fact that some reviewers were viewing on the iPhone 5 screen, which is better than the 4s screen.
