I don't know, but I certainly like denoiser a lot - here I've done some comparison renders :
some unfinished exterior scene render with lots of grass mentioned above
https://www.flickr.com/photos/119850875@N05/25134751849/in/datetaken-public/ - 30 min without denoiser
https://www.flickr.com/photos/119850875@N05/24875561833/in/datetaken-public/ - 30 min with denoiser - yeah some details are lost like tree reflection in a car's window got a little overblurred but still the whole image looks better imo
and some interior ones where the denoiser is way more useful

I know the examples aren't the most beautiful or refined ones but I think they illustrate the denoiser's work perfectly, imo it just kicks ass nothing more to say )) 
Well maybe one thing, post render control of denoising strenght and pixel distance is surely needed but even now one can do it later in photoshop using vfb dump which already contains both filtered and unfiltered Beauty passes\channels even if those are currently not selectable in renderchannels.

Great tests Antantas, the interiors show the potential so much ! Big flat walls, it's exactly where I will use this predominantly. Those just never clear, never ever. Totally kicking ass from what I've seen so far.

Great x2, so this is looking like one seriously good release coming up. No chance proper glossiness scaling will make it into release ?

Hm, the denoiser shouldn't kill the reflections of trees like that. What are the material parameters of the glass?

One more thing. It seems that in VCM mode denoising does not work at all.

First image 50 pases. denoising 1 adaptive on Bidir\VCM

Second image 150 pases denoising 20 adaptive on Bidir\VCM

Third image (sorry for crapy quality too long rendertime) 10 pases denoising 1 adaptive on progressive

Yea, both adaptivity and denoising work only with progressive renderer at the moment.

Yeah it probably is material related - that car model was ripped straight out of fallout 4 with all it's physical material\shader maps and some lazy (and by that I mean really lazy) material and model tweaking on my side which took no more than 5 minutes. It was some time ago and was intended for some remodeling practice but as I got preoccupied with some work I totally forgot about that unfinished scene until now, after your post I opened it again, looked at that glass's material settings and geometry and found out what I forgot to put shell modifier on to it and because all the glass itself is one single geometry piece + material got no thin(no refraction) ticked that, of course, couldn't go well)) Still it was put there just for the sake of making that testing a little less ugly and unappealing and not to show any skills or anything like that look at that gloriously reflecting tire rubber material - skills are not shown that way for sure (shame, shame, burning shame)) I attached the car model itself with all those uncorrected errors if you want to test it yourself but honestly nothing good to see there ))

Please, do not post models that don't belong to you and/or aren't free to distribute. [moderator]

My 20% noise limit rule. For me, it seems to produce the best results. With Adaptivity enabled and denoise at default, render times are fractional.
A negligible difference from my perception, that produces similar results, in up to 70% less time. 
(40hrs using the new build), and 2 projects later. :)

Has anyone experimented w/ noise limit?

What a resolution of you renders?
It is highly dependent, i think///

Interesting point. Just rendered a 4K, and a 20% noise limit kicked it down to :) 28 passes. Past tests @  0% noise limit, would render @ 40-50 passes.

0% noise limit should take LONG to render, if ever. Are you sure you have pass limit set to 0?

Which installer or file groups are required, to update my corona 1.3 Legacy version ? (using 3dsmax 2014 x64)

Installer automatically will recognise if you need legacy version and install correct one. If you want manually copy files from dropbox, choose files from "2013-Release-Legacy" folder.

In the past, have set it to 100 pass limit, 0% noise limit and it would stop @ 50 passes. So, I'm still trying to figure out the best use of noise limit.
Unlimited (0) pass, how do you know the correct noise limit %?....experiment w/ region render?

It should be more or less consistent across different scenes. Similarly to noise threshold in V-Ray. You either set noise limit to 0 and pass limit to some number, or you set pass limit to 0 and noise limit to some number. But it doesn't make much sense to use both at same time.

Wonder how noise percentage is calculated? I have some really simple scene - simple object with basic materials in white studio, lit by single HDRI. Pass limit is set to 50 and noise to 2%. Without adaptivity it renders in about 2 minutes (50 passes), with adaptivity it takes about same time (20 passes, 1,3% noise treshold). After denoise pass both images looks identical. I think it's perfectly normal. Strange things happens when i assign override material with CoronaWire map. Without adaptivity it takes about 2 min and with adaptivity - 4 min (50passes, 2,1% noise). After denoising both images looks identical. Question is why adaptivity struggles with wire? Could it more effectively distinguish texture from noise?
