I've been using DxO's PhotoLab for several years - it's the program from which PureRAW was extracted -and it affords lots of fine control over the denoise function.
I tried out the trial version of PureRAW and was amazed that they had removed all that control from PureRAW as well as the many other functions of PhotoLab that are similar to Lightroom, which I also have.
I let the PureRAW trial expire and stuck with PhotoLab as my principal editing program, though I sometimes send DNGs from PhotoLab to Lightroom (it has a button to do that) for things PhotoLab doesn't do, like creating panoramas from multiple shots.
Things that recommend PL to me over LR:
1) As a test lab, DxO creates its own auto-correction profiles for things like geometric distortion and vignetting.
(They're sometimes a little slower than LR to add a profile because Canon tends to help Adobe with this while DxO has to get its hands on the item to test it.)
2) I can create named groups of settings to apply to pictures - and can make any of them the default when opening pictures.
3) No "catalog import" step - it just browses the disk directly to select shots to work on.
Though I shoot JPEG+RAW, I put them in adjacent folders, so - for working speed - I can choose shots to work on by browsing the JPEG folder before finding them in the RAW folder - I have an old laptop that was running Win7 when I got it, though it's running Win10 now.
