For me it has levels:
a) put the compressors and eq that are needed and see how it sounds.
Many of these are emulated analogs and also bring something more to sound - like tapesims and console emulations do.
b) if something lacking, then I might try either KMT or NLS to see what it might bring.
c) maybe try NLS buscomponent on a bus or master when most leveling is done
d) And when putting limiter on master I might try NLS buscomponent again.
I'm still a bit afraid just to throw things in on every track without seeing a specific need. Too much of the goodies just bring mud to full mix.
Saw the promo video for J37 and the idea to throw this on every track is never what I would do - typical sales talk in my view. What that does might eliminate what compressors or EQ did.
NLS might be another story - have not tried that yet to throw track component everywhere and then buscomponent on master. It does bring some silk on master - but really changes the overall feel of the mix - so not ready for that yet.
