I’ve been a long time Topaz user and have used all three standalone products a great deal. Photo AI imo has not ever got the capability of Denoise which is perplexing to me. I honestly would have liked to see them stick with the trio. Anyhow, about a year and a half ago I switched over to DXO and have been extremely happy. I still do occasionally run a file thru Denoise but DXO is far superior in retaining detail. I do occasionally try photo AI but it just does some weird things to images. With Sony files I find that it gives them a magenta hue as well as tries to sharpen every image. I haven’t tried the last update that came out a week or so ago but really haven’t seen anything that’s going to make me renew my license in December. I agree with what others have said on here regarding the noise removal inside of Lightroom classic and I think it works quite well, albeit a little slow at times. It’s nice when using DXO pure raw because I can send a batch of images into it for noise removal and continue working within Lightroom which isn’t possible with topaz products. This is absolutely something that needs to be changed with topaz products because once you initiate those programs, Lightroom is locked down until the photos return. Unless something groundbreaking happens with topaz, I’ll just stick with DXO and Adobe.
