Hi, I want to know if the quality of a photo book with iphoto is the same that with aperture,

the photos have the same quality, because I used aperture to retouch it, but for me is easy make a photo book with iphoto, I only imported the photos form aperture to iphoto, and I made the photo book, I want to buy it, but before I want to know which one have more quality or if the method of impression, aperture and iphoto, are the same.

so have both the same quality of impression?

And if the answer is no, Can I export my photo book form iphoto to aperture? how?

Thanks a lot
