I think it does really well for 80s metal. Channel 2 can go from barely clipping to full-on metal, it's really versatile. Being able to switch between + and - via MIDI in the next version will be even better. Channel 3 can be dialed in for great 80s metal sound, too. It's just a little more compressed and a little thicker than channel 2, which can be better for leads. Both channels can get very modern, too.
I think the trick is in how (little) one uses the mid-cut. The best sounds I've found only use a little of mid-cut. I use it kind of like a Pultec, where you can boost one frequency and cut another frequency that's very close to the first frequency. That way, you can create somewhat resonant peaks and valleys that you couldn't do with a typical tone stack. Herbert sounds incredible out of the box, but spending some time learning all the ways to dial it in really pays off.
FWIW, other than the 2 Peters' demo, I have never heard any clips that really do the Herbert justice, not even close. It's just such a versatile amp! Great cleans, great crunch, gets brutal like *nothing* else, modern, vintage, and everything between. And the best part, to me, is that it all sounds unapologetically Diezel.
So, basically, I don't think it would be too much for what you're looking for.
