As already mentioned, it's really for deep editing rather than the lighter touch that LightRoom offers. I love it, it's very powerful, well supported and does not require a monthly subscription. What it is not though, is a photo library (although that is in development).
I find that LR is great for editing / organising pics, and then I use Affinity Photo to do the serious editing I need (you can choose 'edit with' from LR and go straight to AP). Once Affinity release something that acts like a photo library then I will probably drop Adobe products and their subscription model altogether.
I'd certainly recommend AP as a photo editor...it's top notch.
