Cannon Rebel XS 18 Or Nikon D3000?

Which one could be better? And more worth it?
Added (1). Sorry about the Rebel XS 18, I ment Rebel XS

I own a Rebel XS but I've never heard it referred to as an "XS 18" - where's that coming from.
I've had my XS for well over a year and am getting exellent results. In fact I have two Canon dslr cameras - also the t1i - both are excellent.
Actually there's no better or more worth it - both are excellent - so just choose one.

For about $150 more you can get a Canon T1i/500D or Nikon D3100. Both are better cameras and include HD video
Which is best for you, YOU will have to decide by visiting a camera store and holding each in your hands
