WHICH CANON REBEL IS THE BEST?

So I'm about to go on a trip to Europe with my best friends. I am going to buy a canon rebel, i wanted to buy the T1i but my best friend already has it and would be pissed if i got the same. I'm thinking of the XTI but is that even a good model? Which canon rebel do you guys think is the best? I'm not looking at the beginner cameras such as XSI and the XS Also is the T1i the only camera that does video?
