Between the top LCD and quick dial on the rear of the camera, the 60D has some ergonomic features you might like. If you've got the ability to play with a mid-range Canon, you can try changing settings in some of the modes you typically shoot (Av, Tv, etc.) and see if you like the addition of the control wheel on the rear of the camera. My sister's got a D5100, for instance, and every time I pick that camera up, I feel like I've got to go into a menu to change something that's got a dedicated button on my Canon. These ergonomic changes are highly personal -- the things I like might not necessarily be important to you, so be sure you're not buying a camera based on features you won't use.
Clearly, the D7000 is going to be closer to the 60D in terms of those ergonomic features -- it's got the top LCD and more dedicated buttons, and it'll have the benefit of being more familiar to you, too. One of the features the 60D lost, incidentally (compared to the 50D) is a full set of custom modes. My old 40D (as well as my 7D) have a "C1", "C2", and "C3" setting on the top dial (where "M", "P", etc., are set), and I can store a complete set of camera settings in them. It took me a bit to figure out how to use these, but I rely on them heavily now. I led a photowalk last weekend where I alternated between tripod-mounted macro shots and handheld candids of the other photographers, so "C1" was ISO 100, mirror lockup, Av set to f/22 (or whatever), one-shot focus and drive, and so on, while "C2" was set to a higher ISO, continuous drive, no mirror lockup, and so on. Switching between these two types of shots, then, was instant. I was floored the first time I picked up a 60D and found those modes missing.
I can't speak to all of Nikon's features, and I certainly don't know which of them are important to you, but I've come to appreciate that the camera is a tool for helping you produce images, and the extent to which the camera works with you and for you is probably more important than a per-pixel comparison.
