"I like knowing that my lenses are true to their focal length"
I'd say this is the number #2 reason I switched to FF. #1 reason is that Canon doesn't make an L-quality wide-angle zoom for APS-C. If you want to shoot landscape you're stuck with the 10-22. Not a bad lens but mine constantly had little problems. It's was clearly lower build quality.

Maybe your images are not marketable?
I currently own a Canon 60D and for a while was certain I was going to upgrade to FF via the Nikon D600. I went to my local camera shop and played with both the Nikon D600 and Canon 6D camera bodies and changed my mind.
I found the buttons and menu system on the Nikon totally foreign to me. The menu system in particular felt kind of tacky. It had a built-in flash and creative exposure modes that I would never use. The LiveView was awkward in that it doesn't allow changing aperture while engaged. Then of course there's the issue of the sensor oil/dust problems and me not having any Nikon lenses.
The #1 criticism of the 6D has been the number of AF points. I find this to be pointless. If you need to shoot moving subjects then you shouldn't be considering this camera in the first place. Look to the 5D3 or 7D. I am a landscape fine art photographer. I'm almost always shooting manual focus, bracketed manual exposure, from a tripod. Add in the low-light capability and it's a perfect fit.
Time is obviously judging the content not the execution. Without a back story none of these are particularly good photographs. We are presented with a camera-phone snapshot of a boy crying. Why? Did his soccer team lose? He dropped his ice cream? Oh his father was killed. How? Was it a lawnmower accident? Oh he was killed by a Syrian army sniper. Ok now I get it. Yes that's a "Photograph of the Year"!
Time is in the business of selling human tragedy. This is what they reward. The technical execution of the photograph is secondary.
