It's my only amp, but I gotta say that it excels at blending in particular as opposed to going at it solo.
Lasse: +1 on the "sweep on three all the time for modern metal." I knew I couldn't be the only one.
When blended properly with a 5150 or Mesa, I find that it lends density, clarity and an extremely fast attack to the overall tone. It does seem undergained even when highly saturated; it's an insanely defined amp. It's hard to debilitate it to being noise. Notes always ring through clear and every note in a chord is always audible. I always describe it to people who haven't heard one as a tube amp that behaves like a solid state amp (i.e. tube amp fat and harmonics blended with solid state attack and super tight bass). Definitely performs best with a 5150 or a Dual Rec. Anyone who doesn't believe me, feel free to reference the leadoff track from Chimaira's Resurrection for a reminder of what Krankenstein & 5150 brutality sounds like.
