They both will do the job. Personally I like Nikon because among other things, the flash system is a lot better and use any lens made in the last 50 years because they have never changed the lens mount like Canon have. However you probably won't be buying an external flash or using any old lenses so it's a moot point.
Whichever you feel more comfortable with. Both OK. If you can stump up for the 18-105mm or 16-85mm in the Nikon camp (not sure what the Canon equivalent is) that's much more flexible, but of course more expensive.
