Should i get a 16 Or 32 GB iPhone 5 or an iPhone 4S 32 GB?

I have had 3 iPods in the past and i'll i've mainly gotten is games. Now if i get an iPhone i'll use it for games, some that i like take up to 1 GB. I won't just use it for that sometimes i'll use it for pictures, of course messaging and calling.i'll also get apps for facebook, twitter, etc.i'll get some music too. Which one do you think is the right one for me?

If price is not a problem, then get the iPhone 5 32GB or 64GB.

If you want to save sa $, get an iPhone 4S 32GB or 64GB.
