Which camera would be better for me? Canon Rebel XS or Nikon D60?

I've had a Sony Cybershot camera for about 3 or 4 years and I've used it religiously, I loveeee it, but it's old and I'm ready to step up to the next level of photography. I wanted to get a Nikon D60 at first, I had my heart set on it, but then when I wanted to start practicing with a DSLR, I started using my mom's Canon Rebel XT and starting getting used to it and I like it. And when I use my friends' Nikon D60's, they just feel wrong in my hand. Generally, I've heard mostly good things about Nikon, but I've also heard lots of good things about Canon. And the lady I talked to at Best Buy, who was a photographer, told me that between the XS and D60, there isn't much of a difference except the lens that comes with the D60 has image stabilization (see other question I have posted about lens...) and the XS lens doesn't, but the XS has more key points for autofocus....so ultimately, I was wondering from any of you who have one of the cameras but have picked up and used the other one at least once, what are the pros and cons of each camera? Just tell me your opinion on which one you think I should get. And if this helps, I shoot mostly macro and pictures of people. Thank you :)
