"At least in my hands, the scanner files never looked as good- although they theoretically should have been better."
You're absolutely correct. The scanned images should indeed look better that the camera file of any sort of film. And as with all things, there are of course certain exceptions to my previous statement. However, what one has keep in mind is the fact that the procedure of scanning, either prints or film, includes much more than simply inserting the image and pressing a button. With a good scanning app there are many settings that can be employed to produce the best results possible from the original piece, be it film, prints or reproductions of art work, all of which have been part of my business for many years. It's not an automatic exercise, it in indeed a hands-on procedure, one that requires time to perfect.
