Where is that? Here in Spain it's €1349 less the €150 discount, so €1199.

This is just a personal thing, but it all depends on what/how you shoot. I don't really have the use for the 105mm end. I don't even use my Lumix 85mm 1.8 all that much, and that's the longest lens I own for my S5. So I'd personally go for the 2.8 zoom. As I like the larger aperture more. But that's just me.
I actually still own the Canon EF 24-105 L, never gelled with it on my Canon cameras, tried it on my S5 with an adaptor, nothing has changed
Now, if someone did a 17 or 18-50mm f2 or 2.8, my ears would prick up for sure

Received my brand spanking new 28-70, this one is more optical flawed than the previous 2nd hand item. But focus motor was quit though.. I have requested a return label.

There's got to be something wrong with your camera, to have killed 2 focus systems in 2 separate lenses.

Focus and focus motor is just fine
, aberrations are not. It really only happens on close focus, but I think it Is not acceptable. My camera seems then to only devour Sigma 28-70 lenses... really love this lens, that's why I ordered a new one. But for this kind of money (full retail) this is unacceptable (at least by me). Also my last try on this lens.RuleOfThirds

I did some more tests, and it only happens on closest focus distance, at 70mm. If at 35mm I reframe the image so that the object is same size (only background differs), so with 35mm closer at the object this does not happen. If I'm like a meter away (more then double the min focus distance for 70mm) it is not happening. Can some owners try this ? closest focus possible on a black/white at 70/2.8 ? Then I know if this is normal for this lens design, or that is something wrong with it.
On my first entry today with the LoCa I wrote quit, but I ment quiet. So focus, and focus motor is good, fast and silent and spot on.

Christopher Frost's review does point out that close-up performance is not good (I think he used the term "dreadful") wide-open at 70mm. Better at 28, as you found.

Forgot about this yt video. So as designed. I have 30 days to decide. Maybe a bit too harsh too soon. It complements the 70-300 and 16-35 very well. The 24-70 dg dn ii does the same thing close-up @70mm 2.8. And the 45/2.8 also. Maybe a Sigma thingy? To quote close focus figures too close, just for the specs? If they had limited this lens close focus at 60cm at 70mm they would have been roasted also.
I like to get close-up with flowers for example.
No zoom is perfect, 24-105 has “only” F4 and harsh bokeh at times. But also bulky to what I was used to, but on the ok side. It’s also not the sharpest or most contrasty lens. But overall very good.
16-35 is a lot better in sharpness, contrast and micro contrast. Giving the image almost a 3D effect.
The 28-70 is a bit sharper / contrasty then the 24-105, certainly when both af f4 but also already wide-open. Except wide open close focus. In that area the 24-105 excels. This Sigma feels less sturdy then the other two lenses. I even like the s primes build quality better, and those are better weather sealed.
The first one I had I liked very much. But somehow, maybe because I paid a lot more for this new one, I’m a bit more demanding somehow. At least I can now look beyond this close focus issue. It’s as designed and didn’t notice it on the first one so it got me a bit by surprise. I was sitting at my desk and it was one of the first snaps I took with it.
