I'm also not in a major hurry. I'm not seeing great reviews of the D700 kit lens, but I am seeing great reviews of the 5D2 kit lens (24-105) which is a few hundred $ savings if you go with that lens. Another plus for Canon.
Honestly, you'll be wasting your money if you buy such an expensive body and use a kit lens on it. You'll be much better off investing in glass than an expensive body.
The D700 and the 5D Mark II are very different cameras geared towards different people. The D700 is optimized for low-noise high-ISO photography. It's fast (up to 8 fps with battery grip, that's almost as fast as a D3 or a 1D Mark II or Mark III). The D700 has the D3's AF module.
Contrasted to that, the 5D Mark II has higher resolution, but it's a slower camera. The AF module is old: it's the same that is found in the 5D and even then, it wasn't really fast. Even worse, it seems to be taken from a camera with crop sensor, because the AF points don't line up with the rule of 1/3rds:
It seems to me Canon has intentionally crippled the 5D to ensure it will still sell more 1D/1Ds bodies. Before anyone hits reply and starts typing: I'm not bashing the 5D (Mark I or Mark II), they're great cameras, but it's more geared towards people who don't need a blazingly fast camera (and to be honest, how many of us really
need more than 5 frames per second?). Landscapes, people photography, etc.
Regarding lenses: there is a consistent rumor that Canon makes better lenses. None of the reviews seem to indicate such a thing. If you're talking about individual lenses, then, yes, there are lenses that are `better' that what the other company produces. But overall, it's quite even. And even if there are differences, they are typically tiny and practically irrelevant, unless you make a habit of photographing bathroom tiles or looking at the corners of your images at 100 % magnification.
