Canon 60d, 7d, or Nikon d7000?

I've tried all of them and they all feel great though I don't like the 60d's buttons. Which do you suggest from your experiences? Just looking for a bigger/ more solid body.

7D for sure.

If you don't like the feel of the 60D then you should instantly cross that off your list of possibilities. An uncomfortable camera will never feel right.

What is your current camera body?

If you have a Canon, get the 7D.
If you have a Nikon, get the D7000.

Don't be switching camera manufacturers when you already have money invested in lenses/equipment. Lenses and accessories are not transferable between manufacturers, it would be a waste of money to change from Canon to Nikon or vice versa.
