Canon Rebel XS vs Nikon D3000?

Which is the better sports camera? Both camera Kits are on sale and I have been wanting one. I take pics of Horses running, jumping, bucking, rearing etc. I also take pictures in the evening and during the day. Indoor and outdoor. The Canon kit has an EF-S 18-55 mm f/3.5-5.6 IS lens, 2 GB memory card, Bag, and all the cords. The Nikon kit has a 18-55mm Lens (Non VR), Nikon Camera Bag, 2GB Memory Card and all the cords. Both also come with instruction packets. I'm 15. I'm very familiar with Camera's, though I have never used a DSLR aside from My High school yearbook sponsor(I'm on the Yearbook staff and am one of the few that she allows to handle the camera). I will learn to use whichever camera I get. I hopefully will be able to get different lenses in the near future. Which camera would be better for me? I want clear, crisp pictures of the horses(no blurred feet or heads) at any time of day.

Rebel all the way. I have one and they are so amazing. It takes the best photos and plus canon makes more products than nikon and they are much better

Canon Rebel Xs

• Bigger Sensor (Rebel has CMOS and Nikon D3000 has CCD)
• Canon Rebel has Live View for studio pictures
• Viewfinder a bit bright on Canon Xs vs Nikon D3000

"I want clear, crisp pictures of the horses(no blurred feet or heads) at any time of day."

Both are decent beginner cameras, but neither have the frame rate necessary to do action sports with any great consistency. In addition, the kit lenses are nowhere near fast enough at their longest focal lengths to give you fast enough shutter speeds to freeze the action of moving horse feet in any lighting except for the very brightest part of the brightest day.

For freezing fast moving action like horse feet, you will need a lens with a maximum aperture at the long end of no higher than f/2.8. These lenses usually cost over a thousand dollars. You might get away with a fast 85mm or 100mm prime lens… Those will only cost you about $400. Anything less than 85mm focal length will not get you close enough to the action.
