I am in the market for some noise reduction software. I am currently trialling Topaz Denoise AI, ON1 NoNoise AI and DXO PureRaw2.

If I buy Topaz I can get all three packages (Denoise AI, Sharpen AI, Gigapixel AI + the new Topaz Photo AI as a bonus). The price is around $275 AUD. I have tested it and like the results, but this price is for a one-off buy - I would prefer to be on some type of subscription which includes all new updates which is not offered.

ON1 is on a subscription but is very slow on my computer.

DXO PureRaw2 very good as what is does but lacks any user input and once again is at a one off-buy price of approx $200.

Does anybody have any experience with the above software and could recommend one over another?
