I was pleasantly surprised after buying the 6D sight unseen. My camera collection includes 1D2's, 1Ds2, 1D3 - I've owned a 5D, 20D, 40D, and had a long love relationship with a 5D2.
The 6D is ergonomically different than most of the rest, and it fits my hand like a glove, allowing my fingers to reach almost everything I need to with the one hand.
It's hard to find much wrong with the camera - the AF layout is a little tightly grouped in the middle of the frame - but I only ever use the center point so it's a non-issue for me.
I'm content to wait for the next FF breakthrough.... and can resist the urge to have a 5D3 in my bag.
