Saturation and harmonics

Hello!

What is your approach and tools for saturation and harmonics?
Wide-band, multi-band, pre/deemphasis, type, wetness?

I'm not sure on this subject.
I hear use of bitcrushing, trashing and overdrive,
and I'm often thinking "This is not for me/ my taste".
Yet, tube, transformer, console-emu, adding weight here and there, softening transients -all those things I like.
Is it much about the amount of harmonics?
Or is it very different styles?

I tend to use/like Sknote Strip and Mjuc. I like the Rocket > Impetus and ThrillseekerXTC,
but I'm looking for more understanding on this subject
and maybe some new tools/workflow.

Thanks!
