Personally I would prefer the D80, because to me it seems better built, I prefer the controls, it has more metering options, a brighter viewfinder and various other little things that make it more attractive to me. But like you said, they're both great cameras, so it's really got to be a matter of personal preference and may come down to which 'feels' right to you when handling them in a store (which I strongly recommend you do before buying). Do bear in mind however that the camera body is only part of the SLR system, so you might want to look at what lenses, flashes and other accessories Canon and Nikon offer and how they compete on performance and price. For example if you want to mainly build up a collection of fast prime lenses Canon's seem more competitively priced. Also consider whether you're likely to go for a higher-end camera body later on, and if so then what will be your priorities? For example would a full-frame sensor be important, or would you be looking for something with the build quality of a D200? Just a few things to think about... but it' still got to be your choice.
