IMHO Topaz sharpening, denoise and gigapixel algorithms are better than Adobe's algorithms. Most of the time I use LrC and PS sharpening and denoise, which work well if the original image is in pretty good shape. Topaz shines when the images are not in such good shape. Topaz does an amazing job at removing subject and camera motion or when the image is out of focus. and is better at reducing noise, especially in shadows. I have rescued images with Topaz that I could not with LrC or PS. So I have both an Adobe subscription and Topaz Photo AI and Gigapixel AI upgrade package. What I don't like about Topax is their business model. They plain suck! We buy products like Sharpen and Denoise, which they end up discontinuing to sell you a new program like Photo AI, then there's the annual cost of bug fixes and upgrades... I much prefer the Adobe model of a monthly subscription fee where you get amazing feature enhancements as well as bug fixes and performance improvements on a pretty regular basis. For example, I did not pay anything extra for the PS Beta version with image creation / enhancement AI.
