for rt's with too much distortion like somehow a boss metal zone gtr pedal has been somewhat maxed out.
That's the only way to use it

1.. examples of too much way over the top distortion imho.
Imho these examples sound find in context for me, in that most of those styles want the ultra-saturated guitar tones. Your examples of "good" styles are completely different genres which would not want that level of saturation.
These days though,
modern metal doesn't use nearly as much distortion as metal from the 80s or 90s.
