As buggy as it is, Luminar is the best and easiest for sky replacements. Before that, I used Landscape Pro. I couldn’t use DxO as I shoot Fuji now.
When I shot Canon, I tried shooting just jpgs a couple of times, but like you, I still ‘touched’ every image, so may as well shoot raw. I’ve been so happy with the Fuji jpgs.
Spoiler alert: At the end of all this, I’m sticking with Lightroom. It works, I know it, and it’s relatively cheap. I like ON1 and could use it. I wanted to like ACDSee and liked a lot of things about it, but I just couldn’t get decent images out of it. I’m sure that was user error.
