Lightroom is amazing at organizing your photos while allowing you to do some major editing with ease. It also has tagging capabilities so you can find your pictures quick (which is great when you have 1000's). Another feature I love of Lightroom is how easy it is to submit pictures for stock footage.
The learning curve of Lightroom can be pretty steep and the Adobe tutorials are kind of skimpy. Fortunately, there are plenty of YouTube videos of tips and tricks you can learn from. Also, there are now 2 versions of Lightroom. Lightroom CC (which is cloud-based) and Lightroom Classic which is desktop based.
If you need to edit and organize your pictures you will be hard-pressed to find a better program. Make sure you decide if you want to use Lightroom Classic (Desktop) or Lightroom CC (Cloud-Based).
Lightroom Classic allows you to quickly organize and edit your pictures from a shoot. Also, once you find a look you like from a shoot you can create a preset from that and then apply that same look with a couple of clicks of a mouse.
For business it allows me to quickly create and organize photo collateral for my website.
