This 2-part series by D.A. comparing the 3 lenses is great. Really gives one good insight into their strengths and weaknesses. Bottom line seems to be, for real world use where most of your shooting is hand-held the Tamron looks like the lens to have. If you have a body with an excellent sensor with in-body stabilization, like the A7r II that Dustin references Paul has (the fellow that loaned him is Canon 24-70mm 2.8L II), then the more obvious choice is the Canon.

A few other aspects to test would be how do all three handle flaring, coma, aberrations? TDP indicates the Sigma doesn't fare well. (Or was that LensTip?) Regardless, zoom lenses by nature (physics) struggle more to control flaring.
The worst picture ever is the one not taken: so shoot, shoot, shoot! Know your equipment first however to avoid as much as possible, bad photos. ;-)

Shooting with a Canon 40D & 7D, w/70-200mm f2.8L IS I, EF 24-85mm f4.0-5.6USM, Vivitar Series I 400mm f5.6 Olympus mount w/Fotodiox converter.

I see Dustin Abbott has posted his full review of the Tamron 24-70 G2 now (and he posted his Sigma Art review a while back)
https://dustinabbott.net/2017/10/tamron-sp-24-70mm-f2-8-di-vc-usd-g2-review/

Dustin seems very happy with his 24-70 G2 - and he gives it the edge over the Sigma Art - but I'm sure I saw someone here (Jopa?) say recently he bought and returned one because he wasn't happy with the AF.  Anyone else given the G2 a go?

After watching various parts of Dustin Abbott's two videos (the ones linked above), to my eye (based the images in the videos) I'd rank the lenses in the following order for IQ:  1. Canon 24-70L 2.8 II,  2. daylight,  3. Tamron 24-70 G2,  4. Sigma 24-70 Art (although pretty close to the Tamron really).

Whether better IQ when viewed at 100% on a computer screen is going to be noticeable in a print or when the whole image is viewed on screen, and whether the VC/OS of the Tamron and Sigma mean you are more likely to achieve better IQ in real world shooting (will depend on how often you shoot handheld at relevant shutter times), are good questions - and of course there is a cost difference - but my enthusiasm for the new Tamron has cooled a little.
6D | 24-70 4L IS | 70-200 2.8L IS II | Sigma 35 1.4 Art | Sigma 50 1.4 Art | Sigma 85 1.4 EX | 1.4x mk II

The G2 review is live! Bryan is saying 90-95% accuracy, but with the center point (which was true for me if I wasn't changing distance). The off-center points "did not fare as well", plus focus shift as a bonus :)
