I'm currently using those two (D700 and Nikkor 24-70) and I can only compare to the previous 28-70 Nikkor, no idea about Sigma or Tamron performance on the D700. However, two different salesman I deal with locally told me to stay away from Sigma due quality issues, they said risk of a bad copy is just too high. Since I could afford the Nikkor at the time I did plunge for it, and now I'm quite happy, in fact it's the lens that I use most often.
My 24-70 copy seems to be quite sharp right from f 2.8 with good corner performance and it's quite contrasty as well. I'd say great lens for travel and landscapes ..and BTW excellent AF.
The previous Nikkor 28-70 was less contrasty and it's resolution in the corners seemed lower, but on the other hand it had a more pleasing skin rendition, so it was more suitable for portraiture work. In my opinion it's still worth looking for on the 2nd hand market..
If you have a chance to borrow or rent those lenses, for a couple of days, you could get your own take on the differences, or maybe change the idea of a preferred lens setup ? <img src='http://forum.photozone.de/public/style_emoticons/<#EMO_DIR#>/smile.gif' class='bbc_emoticon' alt='

Your Nikon is twice the price. There are quite a few users of the Sigma who are very happy with it.
About quality issues... have you gotten your Nikon 24-70mm f2.8 fixed by Nikon concerning the light leak issue around 55mm?

Do that, before it is out of warranty... of course, as it is a production fault, it should be covered outside the warranty period too, but you know how difficult it is to fight bureaucratic "service" organizations!
