DT has improved a lot in terms of processing, and results you can get. Easily up there now with others, NR is good it was poor, details also excellent. Speed is much better. Map works, can add borders/text it's got enough selective editing features to please most. I keep it around as I play with it and sometimes use it. If I have 100's of shots to work through, DT would take ages it's just a no go for tasks like that. It's fine if I do landscapes or small shoots, even then there is just "slider" overload. Many could be simplified, some got rid of entirely or integrated into others.
Looking at the devs, they don't seem to be willing to change the UI - so I don't hold out much hope, still you never know
Luminar is better since last tried it, but still a delay loading previews of images. They say there is an update next week so will wait for that. Again we're in a mixed bag, luminar has solid workflow - decent results, missing some important stuff though and basic DAM very basic at the moment. Nobody seems to quite get it, yet. I gave up on lightzone it seems to have a zombie developer who once a year does a very minor bugfix - just not going anywhere that program which is a bit of a shame really again had a lot of potential.
I'll keep trying stuff, it's not looking too likely I'll be deleting LR soon though. Don't really want to use 3/4 software programs when all I want is one!
