I don't get free versions or payments from any of them. Not all folks are aware of stuff that is available.
Let's just say I am down to a few left on my Mac that I use. But it could be a brave new world by the end of Q1 2018.
I use LR, Nik (ocassionaly), DXO viewpoint (although I have optics and fimpack as well).
DXO I got free from work. As I did some of the earlier Macphun and Nik (when it was paid). I've got a copy of Pixlemator as well but can count the times on one hand I've used it.
I still have an old copy of OnOne too, but gave up on that years ago.
I just find LR does most of what I need and I'm a lazy editor. If it's not done in a few minutes, I'm done!
