This thread is proof that Canon's marketing of the 6D is working like a charm.
To say that there's no comparing the 6D to a 5DIII is absolutely ridiculous. They're both full frame digital SLRs that use the same processor and very similar sensors and they're about the same age. And guess what, both take photos.
I believe you're not putting as much value into "overall usability" than others, which may have led you to make this statement. Regardless, I don't think anyone is arguing image quality here, and I'm pretty sure we know they take photos 
Really the ONLY thing worth mentioning on the 5DIII over the 6D for someone who's really just focused on taking pictures is the AF.
Yes, and amazingly, the OP mentions this several times in the original post as being very important to him. No doubt the cameras are both very good, but the 5D3 is just better for some people, especially those people needing 3rds AF operation or performance AF.
Stuff like a %100 VF and 1/8000 shutterspeed over 97% and 1/4000 is ridiculous to argue over.
Well, it depends. If one does a lot of critical composition work, the 100% VF might be nice. Someone who shoots outside and large aperture might really appreciate that extra stop without having to use an ND filter.
I love how the argument comes down to a joystick... really? That joystick is worth the extra $1000?
Not really. It seems you've completely disregarded several other aspects of the 5D3 vs 6D to focus just on this rather ridiculous point 
Dual card slots - Extremely important for some people.
6FPS vs 4.5FPS - Doesn't sound like much, but it is.
Shorter shutter lag - Again, every bit helps.
AF - no contest.
Dedicated FEC button - Some people REALLY need this.
Larger rear LCD
Orientation-linked AF (does the 6D have this? Unsure)
And yes, a joystick.
I find it hilarious that people feel compelled to spend the extra $1000 on a 5DIII just so they can have the label of a "pro" product over an "entry" level camera.
I doubt many people are spending the extra money "just" to have a "pro" camera. I agree if that's the only reason, it's ridiculous. I believe you just don't place the value on some features as much as others, which is fine.
But, let's reverse your entire argument - "I find it ridiculous that people can even compare the 6D to the 5D3 - the 5D3 has a lot of features missing from the 6D that when taken into summation, equal a better overall camera."
My above assertion is equally as false as yours because we can only speak for ourselves!
6D very obviously suits the OP's needs, why tell him to throw away more money on stuff he'll rarely ever need?
Well, I think some people are recommending the 5D3 because the OP typed:
I really would like to have its extremely versatile AF. All the other extra features don't really intrest me (except for the 100% viewfinder).
and
I also like the "Single Point Spot AF" of the 5D3 which seems very nice to nail the focus on tiny objects/spots (e.g. the eyes)
and
If focus errors because of focus&recompose didn't exist, I would immediately go for a 6D. But since I want to apply the rule of thirds to (most of) my pictures, I'm really afraid that focus errors would render the 6D useless because the AF points on the 6D are so centered
Granted, he also makes some very valid points for the 6D, so all we can do is make suggestions 
Here's my logic in the matter - If one is happy with the 6D, then one has saved a lot of cash.
If one is not happy with the 6D, you're stuck with it (assuming you haven't returned it). One can always add the wifi capability to the 5D3 (at a ridiculous cost) but one cannot add the AF to the 6D.
Both great cameras, but only the OP can decide what he values more, and both sides of the argument are equally valid on the 6D vs 5D3
