So, I've got a friend that I'm helping to merge a couple of large stores of photos, and then I'm going to try and get her out of using iPhoto (ugh...) and onto a real photo management system like Aperture or Lightroom. Personally I use Lightroom, have been since LR2. Other than it being a cross-platform license if she goes back to using Windows, what's LR got that Aperture doesn't, or vice-versa? What are people's experiences? I figure I'll have to spend at least a couple of hours familiarizing her with the basic usages of the software and how to manage photos with it, but which one would probably be easier to pick up & use for someone who is not primarily a photographer and mostly needs a better quality (and less slow) photo management/editing application? She's got >65K photos, and her iPhoto is just crawling and slow.
I believe she has a Canon T2 or T3, and mostly shoots JPG but occasionally RAW. Or is there something that'd be even better for her?
Also to note, she's only looking to buy a perpetual license right now, so the Adobe CC w/Photoshop is not really of interest to her.
