You should not solely depend on what's on paper to decide which body is better at a certain price point. With the bodies you've mentioned, differences in image quality will be much more appreciable with the lens you use. Advantages you read on paper may have less relevance in real-world scenarios.
You can buy the most expensive DSLR body or the one that on paper is "the best" but if you put cheap, mediocre, not so optically sharp glass in front of it, you'll be wasting most of its potential. This video explains it very well: http://www.youtube.com/watch?v=hk5IMmEDWH4
Maybe you should handle the bodies to determine which feels most comfortable and perhaps you should consider which lenses you'll buy.
It could turn out that the body that's "worst" on paper is the one you prefer it terms of ergonomics and if you like the ergonomics, you'll probably use it more and the more you use it, the more likely it will be that you'll take great pictures.
I'm not saying the cheapest, least featured body with a sharp lens is guaranteed to suit you for every occasion since there are specific requirements for features that appear in more expensive bodies, I'm just saying that in terms of pure IQ, the lens generally has a much greater bearing on it than the body you put behind that lens.
