I recently purchased Photoshop Elements and Premiere Elements 12. I have many, many pictures from several years on our hard drive and would love to be able to better organize and tag them, etc. I have recently learned that Photoshop Elements can do this for me. I have also recently heard that Lightroom is good for this. Before I start importing thousands and thousands of files into PSE, I figure I should determine if I should use Lightroom instead. This would obviously come at an additional cost, so I would like this forum's help in explaining how Lightroom might be better than PSE for this function so that I can determine if it's worth the extra cost.
The PSE Organizer has fewer features and more bugs than Lightroom, in my opinion
Lightroom has more features for searching and more metadata fields for your use if you need them
Lightroom offers the ability to geotag your photos and display them on a map
Lightroom can streamline your workflow, so if for example you want to do the same things to multiple photos (including applying the same edits), this is much easier in Lightroom.
In general, my opinion is that Lightroom's Library Module is a superior piece of software than the PSE Organizer. In general, my opinion is that the user interface for Lightroom's Library module is a superior interface than the PSE Organizer. My opinion is that Lightroom's workflow is smoother and more efficient than doing the same things in PSE.
But some people love the PSE Organizer. It all depends on what you want to do. Your best path forward is to download the 30-day free trial of Lightroom, view some tutorial videos about Lightroom (don't skip this step), and compare for yourself the PSE Organizer to the Lightroom Library Module (and other parts of Lightroom as well).
