I have used Topaz DeNoise AI for several years, and rely on it in my workflow, especially for choral choir concerts in poorly lit concert halls/churches.
When Adobe added AI Denoise to LRC I tried it, found it's results similar to Topaz, but the amount of time required to process images in LRC were greater than 5 minutes/image.
Topaz processing times are about a minute/image, so I have gone back to Topaz at least until I upgrade to a higher-powered GPU/CPU processor.
My processing times between Topaz Photo AI and Lightroom Classic Denoise AI are about the same and a lot less than 5 minutes. I'm not sure but I think it depends on the GPU you have.
