It's in my sig too but I'm currently on a Canon EOS 10D, old but still pretty awesome, but it tests my patience for sure. I had originally planned on going the 60D upgrade route, but I know that then I'll be tempted to buy EF-S lenses, so I'm looking to go to a 5Dc since I know that I want to go FF eventually anyway.
I've shot a D7000 and I loved it, I have nothing against Nikon and I love their Speedlights, and those front and back adjustment wheels on their prosumer and up bodies are amazing. But, Canon is what I grew up on and what feels right in my hand, Nikon took me some time to get used to changing certain settings that I knew how to do blind on a Canon body. I see it as personal preference over anything else, both have very compelling solutions for every area of photography.
