Joshua,
I had LR and PS for many years and recently decided to try some different products because I hate paying a subscription cost. I'm on a Mac so my LR replacement is MacPhun's Luminar and my PS replacement is Affinity Photo. I have not tried Designer yet but soon will add that to my list of goto apps.
I used NIK for a while and like it but Luminar is much more flexible. However, I still have not found a good photo catalog system like LR.
As far as feature comparison is concerned, while PS has a bazillion tools and features I personally only used about a third of them and Photo has not disappointed. Everything I have used in PS can be found in Photo, some things have different names and it takes me a little longer to hunt for the feature but I always find it eventually.
