14-24 is an outstanding lens. I got a chance to use one a few times. But the range is very limited, and I see it only as a special purpose lens. On full frame, 24mm is standard wide. 24mm on a Full Frame is like 15mm on your XT, quite wide. Both Canon and Nikon make great lenses. I just find that the Canon line-up is a bit more versatile than the Nikon. As far as primes are concerned, I'll be honest and say that I haven't had enough experience with Nikon primes to give a valid opinion on how they compare with Canon.
Poe, I've been asking myself exactly the same question for about 3 months now. I signed up here to get a feel for the canon stuff, and I have read just about every review of the d700 and 5dii I can find. I have also read every review of the lens lineups I can find too. I've gone out and had a bit of a play with the store floor copies to get a feel for them, too.
I am *still* not decided. Fortunately, my funding won't come through for another month, so I still have some time up my sleeve. What I can tell you is that I am leaning very heavily towards the 5dII just now.
The advantages of the Canon that I like are the 21meg files (I will print very big occaisionally, but I am also a bit of a detail whore). I like the native 100ISO, too. 3.9 fps is a little on the low side for what I would like, but I know that realistically I won't be in a situation where I will need faster fps than that. The lack of many focal points might be an issue, but I know they've improved the performance of them in the newer body at least. I coudn't care at all about the video capability. I do really like teh feel of the canon in my hands.
I like the nikon's fps though that shouldn't matter. I really like its bracketing. It also feels good, but not quite as good. And the menu on it isn't very naturally intuitive for me. After looking at them side by side I was still only just leaning to the canon. And it was a line ball.
But one thing I did realize over the past couple of months: My choice isn't really about the body. In 2 years time I am going to be looking for a new body. This camera I get now will become a backup, or even be sold off. Or given away to a deserving party. I will still be left with my lenses.
What I plan to shoot is a bunch of studio stuff, with the odd citywalk, zoo walk or maybe a day at a sporting event thrown in. Plus I will shoot a heap of macro stuff. For what I want, the canon lens lineup is likely to be the deciding factor for me. I will start out with the 85L, and get stuff as budget allows and need demands. Nikon do have some great lenses, but nothing that can compare to things like the 85L, the MP-E 65mm Macro or the other primes I hope to acquire. It wasn't until I figured out that the lens lineup will be more important that my decision started to become clearer. I might be picking up a zoom or two for the walkarounds, and Nikon do make better zooms. But they're not so much better that I would give up the awesome optics the L primes deliver to get a slightly better walkaround zoom.
Figure out what you're going to shoot most. Figure out what lenses you think will give you the best results for those purposes. See if one lens lineup is better for you in that space. Then go back and look at the cameras again.
Edit: There is one other thing, too. I haven't found a nikon community that I felt at home in like I have here.
