At least for my photos of my family and friends. I usually do this in LR because I always shoot RAW, then process, then export the final jpeg to iPhoto for syncing to my iDevices and sharing.
But in my 2014 new workflow, family shots will be shot jpeg (these types of snaps don't need RAW after all) and imported directly to iPhoto with Aperture doing further enhancements since the two can share the same library.
What I like most is that I know longer have to export a final jpeg since I believe (correct me if I'm wrong) iPhoto/Aperture shows the latest version of a photo and uses that latest version as the actual photo.
