I would agree with earlier posts that the lens(es) is(are) important. Your question is however possibly: what is the best trade-off/optimum? There is no simple answer in my opinion and everyone will have some different optimum configuration for a given budget.
As an example, I wanted WR and video, with good Hi continuous shooting capabilities. The market is limited and I went for the cheapest body: the K-7. In turn this allowed me to buy the few lenses that I needed. In this instance, colour, contrast, resolution, sharpness were not the key issues: most modern dSLRs have relatively similar characteristics.
Another issue is the hand feel for the camera body. You must select a camera that you will enjoy, that fits on your hands, with a weight and size that suits you .... It is not all about colour, contrast, resolution, sharpness...
Glass is important, but I would stress that the feel for the camera body is as important.
