I realise I'm biased because I shoot with a D700, but I would personally say that if you don't want the video capabilities, or the reach given by the crop factor of the 60D then the D700 would be the better choice. The D700 may be older, but it's a gem of a camera, and certainly better built than the Canon
If you can stretch your lens budget by about £100 you could pick up a Tamron 28-75 2.8 instead of the 28-105, which is a great lens for the price and gives you a constant aperture.
The 60D isn't a bad camera by any means, and does have a couple of advantages which I have mentioned, but in my eyes the D700 would be the better choice.
