I own the 28-80 2.8 ATX Pro. I read quite a bit before buying this, though I might have missed something this is what I found:
Tokina 28-80 is noticably better than the older model 2.6-2.8 model. THis is from people who used both. 28-80 has a great clutch focus mechanism. I think the onlyu other good mf/af system is the FTM mechanism on L lenses, but for quick switch to full time MF, it is awesome. I can't stress this enough. It is built like a tank. The low quality control issue I think stems from the fact that this lens had problems focusing really close on Nikon F1's (I think it is called F1). It did it with only that particular body. Focus speed - very fast. Probably not as fast as USM but it is as close as it gets; I do not think I missed a shot because of it. It focuses fine in low light as well. I do not own, or intend to own 28-70 2.8L. So I can't compare. But the images I get from this lens are good in my opinion. It is heavy. Almot as heavy as 28-70, and I think bigger. Actually IMHO 28-70 2.8L feels less sturdy than this lens when I handled it at CW of Oregon (evil). Comes with a hood - never noticed flare that much. I am not an expert either. Bokeh....

I could not find better ones online, sorry :-( Let me know if this is good or bad. As for comparison, http://evrimgallery.com/Proofs/Thomas/kathy_thomas_r1_21.jpg was with 70-200 4L , at f4.0. At deltainternational.com, you can find it for $450. I recommend it. It is heavy and big, so I bought Canon 28-105 lens, so I can take it out when I go somewhere and am not planning on a photoshoot. If I am planning on a photoshoot, I will take the Tokina. Quiet AF. http://www.kyphoto.com/thirdparty/tokinaincomp.html lists incompatibilties of Tokina and other 3rd party lenses. 28-70 2.6-2.8 can not be used with Elan II. I think you need a chip upgrade. The 28-80 works fine with everything except that particular Nikon.
