I agree with Reaper and Fusion, there are not much alternatives there, although, and depending on the level and if you're used to layers and comps don't discredit Hitfilm. I know is not as powerful as Fusion but I see it growing every year as a viable alternative just not for fast turnaround or high level stuff yet.
And lightroom, for DAM it depends. On1 is really nice, the price is right and the tools are nice. I feel it's still a little bit clunky, not as polished as say Capture One but as with hitfilm, don't discard it because it looks it's developing quite well. It might be the age but I'm more willing to buy products from developers that listen and help them grow(and I include Blackmagic here). Or it might be my desire to find underdogs and Davids that can bring some fight to big Goliaths.
For photoshop I rather use Affinity photo but in the open source world see the development of Krita more elegant than Gimp.
