My premise was that the 6D is capable of very good IQ - as the 5D2 already was 4 years ago. There's really no surprise about that, being a well-established technology.
What concerns me is how users' opinions vary awfully depending on the brand. In the numerous 5D3 vs D600/D800 debates, Nikon cameras where found faulty exactly in those segments in which the 6D is even faultier (e.g. AF, weather sealing, build quality, etc). All those valid arguments - apparently - no not apply to products with Canon branding. On top on that, the 6D cannot compensate with cutting edge sensor performance and it's a full 300€ more expensive than the D600.
All my favourite lenses are 3rd party (except the 135/2), so I very much don't care about the brand of my body. I'm still undecisive whether to buy a 5D3 or a D600, but if it was D600 or 6D, I would really have very few doubts. Considering the 6D is mainly aimed at crop-upgraders, I'm really dubious about what the concrete reasons for not switching system are.
If you have bought your favorite third party lenses already, then I guess you'll care very much for the brand of your body. If not, then that's the only time you're open to switching systems. Even third party lenses have their own separate mounts for different systems. 6D is only more expensive in Europe but not in Asia. In Asia, some deals for the 6D are entirely better than D600. Even if you found some offering a better deal for D600, you just need to wait a little bit and you can be sure you'll be finding similar deals for 6D. Build quality and weather sealing of 6D is comparable with 5D3. You'll only find the top part of 6D lacking in durability compared to 5D3 due to its being made of polycarbonate and not of magnesium alloy. If you want better sealing, then you have to go for 1D bodies. AF wise, 6D isn't for sports. D600 is better for sports though not much. I'll still vote for 5D3 if you want an all-rounder camera body. D800 is a very good camera but versatility-wise, 5D3 is still the best out there.
