Well that is a very
open question, I don't think I can answer it without you giving everyone at least some information on what you shoot, in which conditions do you shoot, if you shoot video, and so on and so forth.
Personally (that might be my Canon obsession talking though) I think that the 60D is better, especially for shooting video.
If I could give you any recommendation right now is that if you shoot video, go with the 60D, it's a lot better, especially the flip screen (which personally I love
) and better image frame-rates. Also, the 60D has a 3:2 screen that will fit your pictures correctly. Another advantage of the 60D is that it has 2 extra megapixels, but in practice, it isn't too much of a difference.
On the other hand, the D7000 has a higher ISO range and better pictures at higher ISOs. It's viewfinder is superior given that it has 100% coverage while the 60D's doesn't. Also, it's focusing system is a lot better that the 60D's.
I highly recommend for you to check out Gordon's Nikon D7000
and Canon 60D
reviews to see how each camera performs and how they compare head-to head.
