What is the best high iso recover tool?
Unfortunately, somehow, I have several photos that were shot at crazy high iso, so, the shadows have super noise.
What are your best recovery tools/method for this?

You can test DxO DeepPRIME denoising in Photolab 9 or PureRaw 6 at no cost for 30 days. The denoised raw files can be exported as DNG for further processing. I use this method from time to time when processing in Capture One that doesn't have similarly efficient denoising. The quality of DeepPRIME denoising is outstanding.
buggz, were the photos captured as raw files ? jpegs will be harder to fix. raw files are easily handled by Denoise in Adobe software. I suspect you don't have that software or you'd already know how impressive Denoise can be. Default settings are usually OK but for very high iso you might want to wind it back a bit to preserve subject details.
Nowadays I'm too far out of touch to recommend any other software but they're probably all much better than they were even just a few years ago. Part of what makes Adobe denoise so good is the amount of dark-frame sensor testing they did on many cameras with the lens caps on. These days it will mostly be AI-based "training", whatever that means. In the old days it was more about changing settings on simple algorithms that worked better on some images than on others, so using a different program could give better or worse results, but not for every image file.

That's part of what I was thinking about when I asked the op a few (so far unanswered) questions earlier in this thread.
AI Denoise in Adobe software (I usually apply in in ACR) is actually pretty astonishing. I have old photographs made in very challenging low light (e.g. things like birds in flight in pre-dawn and post-sunset dusk) at high ISOs that were slightly underexposed, and I could never make them usable with older tools. But quite a few of them are now usable after applying the AI Denoise tool.
Also, good point about raw versus jpg files. Things like this are another good reason to use raw mode rather than jpg, or at least to shoot raw+jpg in case you need to rescue an image.
Also, dealing with images where the exposure is way off will usually requite more than just NR. Depending on the direction of the missed exposure there can be some issues with recovering highlights or shadows. There are some tricks...
While I'm not thrilled by the overall performance of Darktable as a LR replacement, the noise reduction actually works rather well. I haven't dug into it too deeply. But I found the basic "denoise (profiled)" module seemed to work better than "raw denoise" on the raw files I experimented with. This likely hinges on finding a matching sensor profile in the module. Both modules are totally manual meaning no "AI" features. So you have to push sliders around to find the best adjustments for your particular image. The default Y0U0V0 color mode retains better edge detail so that's probably best unless you have wide areas of uniform color like open sky.
If you're only using denoise occasionally, it could be worth the price (free). If you're processing a lot of dissimilar images that would each need individual adjustments, one of the paid AI tools would likely save you time.
