I find that nibs are more difficult to maintain than creating views in code. You'll spend a lot of time trying to figure out where something is set since you can't do a global search & replace on nibs. If you avoid magic numbers, it's easier to change positions in code without lots of fiddling around.

Since I used Cocos2d (which doesn't use nibs) in one of my games, I was able to update it very easily for the iPhone 5 (despite using some magic numbers) by simply using a multiplier based on the screen size.
