Better is such a subjective word. The picture will have more information in it so it has a wider latitude when it comes to cropping and such. But for uses like the web, printing to 8x10, emails, photo frames, both cameras have way more resolution than those devices use so you would see a difference.
The biggest practical use for the extra resolution is for wildlife photography where getting close is sometimes difficult and cropping is a necessity. The 50Ds extra pixels really help here. I have a few samples I can post up if your interested in seeing them.
ok thats a big part of my picture taking is far off wildlife, so yes cropping will be a factor! and definatly yes id love to see some of your pic samples!
