A point of style: ‘Chicago Manual of Style’ Headlines or ‘AP Stylebook’ headlines?

I know this isn’t directly related to web design, but rather, this is about the most important part of a website — content. I find it hard to decide on what style I want to use for my article headlines. On the one hand, many sites are using Chicago Manual of Style type headlines — a headline where the first letter of every word, except for articles like of, in, and, withfor, etc., are capitalized. But on the other hand, having worked at a newspaper that used AP style, I am partial to AP Style Guide type headlines, where only the initial word in the headline, and any proper nouns, are capitalized. I’ve been pretty inconsistent so far, but I want to stick with one style, and maybe even retroactively correct older articles.

I want to hear from you. Which style do you think works better? First, let’s look at a test headline in Chicago style:

Here’s the same headline in AP style:
