Try the hdr preset of local contrast in DT if you are looking to bump details/contrast … you will have to dial it back most likely but it really pulls things up and even seems to help manage DNR a bit…
I also dabble with ART… are you saying that you only used the exposure tab basically or did you use other modules as well?? DT ones look a bit less saturated and a bit cooler… Just random observations… I often felt I could easily deal with color and saturation in ART but I never was able to really control sharpness and often I got lots of artifacts as well so I would be curious to know if you just did tone and color or you also did a bit more to your images…
The new scripts in the local adjustments tools are quite powerful and really provide even more control in ART…
One other think I would check is the rendering intent if you are looking at exported jpg files… I think and I might be wrong that ART might default to relative rendering which in most cases I prefer but DT does perceptual and the DT default profile has no table to do rendering intents so you would need to swap it out… I use an ICC file from color.org… before that I found at first I was adding some black compensation in exposure and then later using the waveform just dropping the black using the global offset as that was recommended… Using either one of these immediately improved my rendered jpgs making the color and contrast more like I had on the screen… The perceptual render was much better for some images but overall most times I like the bolder image of the relative render… I am only going by what shows in the ART color settings but @agriggio Alberto might be able to confirm if the jpgs use relative rendering…
