hmmn, newbie's input here..
yeah, I believe both brands are great, have a wide range of lenses, accs...etc..etc..
but as what others are saying here you can try both first..to feel it, check the ergonomics,
functionality, features...blah blah blah..however, you can also try other brands..who knows
instead of C & N, you may like Pentax, Olympus or Sony.
This will also depends of what is your main purpose of buying a DSLR - hobby, business..?
..and of course your budget..
The most important thing is.. and as what other ppl said..it's not your C with L, or N with VR, or S with CZ lens but it is whether you have the passion(and u can sustain it) to capture the precious moments & beauty of the world..(naaks).
I use S cos I dun have much budget and currently using Kit lens and a normal tele BUT I can still achieve what I want...well hobby that is..with satisfaction of course

...functionality? not bad with built-in Steadyshot so even my kit lens can tahan, sensor..same as N...blah.blah..(well sorry but I'm not promoting S...:bsmilie
So it's Saturday and you can burn the whole day to try, try and try...have a nice day!
Cheers...(too long..pai seh...hehe)
