There you go the difference gets more obvious at 12800 and 25600.
The lightness of the 6D is more than slight. Put it this way, a 6D with a 24-70mm II 2.8 is lighter than a 5D3 with a 24-105mm.
I agree than 1/8000 and the joystick aren't particularly important. Who needs a joystick when you only have a handful of AF points.
But the LCD of the 5D3 is quite a big advantage, it has more accurate colours and better contrast which is more important than the size. It gives you a better idea of the final product.
The 5D3 has a couple of other minor but useful advantages over the 6D:
In view finder level meter, which also shows both the horizon and vertical, the 6D's only shows the horizon. This is quite a big deal for landscape and architecture shooting with tilt shifts.
DOF preview button in a sensible location.
Dual memory cards.
Rating button, start picking keepers before you get home.
We're on the same page more than you can imagine
I said slight to keep a flame war down... I shot both my 6D and my friend's 5D3 side by side last weekend and the weight difference was obvious. I also agree that the LCD on the 5D3 is better for sure and can certainly be a big advantage, however, I did notice that many of the shots I got from the 5D3 last weekend were underexposed by more than a stop, the only reason I could think this happened (I'm a chimper) is that his auto brightness LCD (which I often wish my 6D had) was over-brightening the LCD for the ambient light making me think the exposure was better than it was... alas, it's my fault for not using the histogram. I will say the LCD does seem more accurate for colors and contrast on the 5D though, I'm glad that's not just in my head!
I hear people complain a lot about the DOF preview button, I've never had an issue with mine, granted, I don't use it very often since most of my lenses (in fact, all of them now) are manual aperture anyway.
The dual card slots are nice, but not necessary unless you're doing critical work like weddings, even then, not that huge of a deal IMO, SD cards are very reliable and you should be replacing them ever 4-5 years anyway to prevent failure.

You're probably going to need an ND regardless. Even on my 5d, if I'm shooting 1.2, I can still blow out @ 1/8000, and definitely use an ND.
Exactly this. Whenever I hit the ceiling on my 6D it's been in lighting where I have to stop the lens down by 2 stops to make it work, ND would be needed either way.
And the 6D has 1/4000 and ISO50... so a 1 stop difference

The high ISO difference may be slim, but it's still useful. And high ISO is the not the only way the 6D and 5D3 sensors differ, the 6D does better in pulling up shadow details and highlights.
Even in non-demanding one shot situations I find the 5D3 to have far fewer focus misses than the 6D. The 5D's AF points are better than the 6D's centre point. The reason for this is likely that the 5D3 has a row of double cross type sensors in the centre, with diagonal and vertical/horizontal lines. Not merely cross types, but double cross types! The 5D3's AF system is so reliable that you can trust the camera to always get it right, which is completely different to the 'trust but verify' attitude I have when shooting the 6D.
However. As fantastic as the 5D3's Af system is, I feel it's utility is usually overstated. I've never run into a situation I couldn't shoot with the 6D's AF system. It is good enough, it gets the job done and leaves you with the shots you needed.
IMHO, if someone is budget limited one is much better off to get a 6D and use the extra to get a better lens, like a 24-70mm II. The 5D3 as I see it is more of a luxury body, the 6D can do almost everything it can for half the price. But the 5D3 is sure worth it if you have the money.
^Again, I agree! The 5D's AF system is definitely fantastic, I'll never deny it, it's an amazing camera for action and just about everything else, but to say that the 6D's AF system is worthless is just a flat out lie.
