The reason real guitarists prefer tubes is because of the distortion.
This is not entirely true. The dynamic known as "pick attack" is also something which solid state amplifier and DSP cannot reproduce with any level of accuracy.
Interesting, but Kemper disagrees with you. Their amps even have a "pick attack" knob.
Solid state just doesn't compare.
Solid state does many things well, but it has its own niche.
Well these days they do compare. Humans can't distinguish between an amp modeled on (for example) a Kemper modeling amp and the tube amp it modeled. A few years ago it was not the case, but DSP always wins in the end.
I call bullshit on your bullshit
