Isn't the bottom line how good the tone is? I could really care less about all this "behaves like ss". That is an old tired argument. Tone imo IS what is important. So let's just talk about the final transducer in the tone chain, the speaker, driven by the Katana, how good is that tone? But what is good amp tone? Some here would say my Kat tone doesn't sound like tubes, but does it matter if the amp's tone is very nice and complimentary the guitar? It has a nice flavor of a warm Fender Princeton meets Vox AC30 meets Fender Deluxe meets ASAT Special. Nothing solid state about this tone, based on what solid state has sounded like. And nothing '90s modeling tone either. Boss just got it right and right is enough for me to love it.
