If your asking between the two bodies I'd suggest spending more and buy the 5d3. You'll be able to capture sports, flying birds, running kids and portraits. You can get nice usable images in low light at 12800/25600 ISO with fast prime lenses and even f/2.8 zooms depending on the lights.
As long as your not trying to shoot things that have erratic movements the 6D is fine. With what the OP listed that he likes to shoot there isnt any reason to get the 5d3. The 6D has generally been received as a camera that has better high iso than the 5d3.
With a 5d3 you can virtually shoot all sorts of situations since the AF speed is fast and accurate and low light performance if very good. Dual memory cards and 1/8000 max shutter speed is a huge bonus!! The 6d is a single card and 1/4000 max shutter speed body.
That really depends. For most people the 6D will prove to be just fine.
Even though the 5d3 is aging the image quality will not disappoint for sports/birding/portaits. You cannot say the same for a 6d.
Im hoping your not trying to say that the 6d has worse image quality than the 5d3. Thats just plain wrong.
IF you buy a 6d you may wish for faster AF. With the 5d3 you'll be less worried about the functions and performance because it's already at a very high level.
This is true. The 5d3 af is very good and something the 6d falls behind in when needing to shoot erratic moving objects. This is the main difference an everyday user will find.
