70-300mm F/4-5.6L IS or 70-200mm F2.8 VC?

The Tamron will do your photography justice. Plus matched with you 6D - with its -3EV sensitivity rating on the centre cross point will be an amazing combo. I agree with trying both. If you can go one further and find a place that you can rent either one, I think would certainly help your decision. In regards to the focus speed, the reality is - at times its like splitting hairs, its close but negligible. BUT to some photographers they would said its worlds apart and reviews will go either way.

Check this review out on the Tamron. It does mention that Tamron has the edge over the Sigma 70-200.

+1 on the TDP review. It notes that the Tamron loses more of its focal length when focusing on a closer target than the Canon, its AF servo performance/accuracy and its AF speed is is not as good as the Canon's. It also has a lower max mag value.

In the US, one could have bought the Canon for less than 2000 during the winter/holiday sales. Right now it's 2500, and the Tamron is 1500. Obviously, your country is different, so the price difference is more significant.

Yup, definitely saw that most reviews placed Tamron right behind Canon and Nikon but before Sigma. Nothing to offend Sigma (since I definitely am waiting for the 24-70mm F2, if it's coming out! Breaking my piggy bank for that!), but Tamron will be the better choice. Canon was on the mind but the price is twice of it. I just want to know how much that gulf between USM and USD would cost me, and seems like you guys are telling me it doesn't justify it. In fact most would say that the IQ of Tamron is equally good, which is almost surprising!

I thing the Matt Granger vid shows examples of the difference between USD and USM.

I personally think the Canon is very quick on a 5d3. Although without having both side by side I can't give you a honest opinion comparing the two....
