Sorry, starting to run low on likes again...
That works for me. I guess personally, it is just that I find jealousy a big turn-off, especially when it goes too far. Envy is fine, it can cause you to work harder and try new things, but jealousy is a problem. To me it is the opposite of love. It is treating someone like a possession, and if I am going to play that kink now days, I want to be the owner, not the owned. The older I get, the less I am willing to be pushed around.
It is a tough choice, and sometimes that might depend on the lighting, as that will change your needs and what you should see in the scene.
I am not sure what I plan to do personally.... For now I am using it it helps with the teeth and some of the hair styles (especially when they have a lot of strands). Now this might change when I get better at lighting, but for now it makes a big difference in some of the renders. There is also the option to render a larger pic and reducing it to remove some of the noise...
What I do know is that noisy images are also annoying and blurry, so kind of a drag if it goes too far either way.
I guess I have to vote 'with' for these, as the blurriness I see seems to stem more from the way the camera is focused (DoF) than the denoiser, but again each scene will have different needs, and you will want to use or not use it depending on each thing.
If you don't use it on these, I would say they could stand a few more iterations though. hehe
