I'm not necessarily preferential to Nikon, I just know a lot of people are very all one and absolutely not the other, whichever those are. Ultimately they're just boxes that capture light, so they'll both do about the same job. But yeah, if I had to choose between these specific kits, I'd pick the Canon just because it's got a slightly stronger telephoto lens, which gives you a bit more zoom to get in close to far-away subjects. In this case with these cameras, a 300mm lens (which the Canon kit comes with) will pull something that's nearly 100ft away to make it seem like it's only 10 feet away. The lens the Nikon comes with does the same for something that's only about 65 ft away.
