Aperture is quite a bit more sophisticated than iPhoto, although some of that has to do with file handling and workflow. It's really designed as a processing/archiving/database program, as is Lightroom.
For someone who is going to be taking a great many photos and needs to be able to sort them, choose the best images, edit and archive them them as quickly as possible Aperture or Lightroom are good choices. If the emphasis is on photo manipulation over workflow Photoshop or Pixelmator make more sense (with Photoshop offering a great more many tools).
If you just need to import photos with metadata and do some basic correction iPhoto is fine.
