I thought I´ll just put in my two cents.
Having owned and played Diezel VH4, Herbert, Hagen together with Mesa Dual Rectifier and Mark V, I must say that the Archon is the better amp (for me).
The clean channel is just bigger and warmer than all previous mentions, and the Hagen has an amazing clean channel, so I´m not jst throwing big words around.
When it comes to the lead channel, it´s hard to explain but it´s just so easy to dial in whatever tone you´re looking for.
It can be fat, tight, mid heavy, scooped....whatever

The Diezels are not that hard to dial in, but the recto is a chapter of it´s own.
I would like to say that the lead channel is a mix of the fatness and chugh from the two-channel recto and the amazing midrange from the Diezels. The gain structure itself is modern, and you can get superattacked and muffled if that´s your thing
For me, the Archon is an amp for life, and I swore by my Herbert and Hagen for a long time.
It´s just so simple and amazing you just wanna rock out!
The fact that it´s not nearly as big or heavy to carry helps too
