Tamron 28 75mm f 2 8 vs sigma 24 70mm f 2 8 dg os hsm art?

I don't have a page for the Tamron 28-75mm f/2.8, so I can't compare the two directly. I'd rather not guess at its specs or price.

What I can tell you about the Sigma: it's a full frame zoom at 24-70mm f/2.8, it's stabilised and autofocuses, and it's made for Canon EF and Nikon F mounts. On APS-C it frames like roughly 36-105mm (Nikon) or 38-112mm (Canon). You can see the full list of compatible bodies on its page.

Both lenses are f/2.8 zooms, so the constant-aperture point applies to each: the exposure stays the same across the range, unlike cheaper zooms that get darker as you zoom in. For the basics, see Lenses. If you tell me what you shoot, I can point you to the right kind of lens for it.
