It's ridiculous that someone would call out 'tubes' as somehow being a kind of nerdy/fake/poseur guitarist connoisseur melodrama. It's literally the most important point differentiation of amps, to the point that almost all tube amps sound better than almost all solid state (at least in the same class).
While someone might possibly take umbrage that 'tubes are not always better' - there's basically no room for someone to say it's a 'petty concern'.
I’m struggling to work out what you mean by “warm” here. By a musician’s definition, low impedance pickups and solid state electronics (usually those with input transformers) have produced some of the warmest guitar tones on record. Even a mid-tier archtop plugged directly into a solid state amp produces _incredibly_ warm.
Distortion (in the musical sense), sure.
The downside is that all of those 100W amplifiers sitting in hobbyist living rooms often don't get enough power to achieve this without being too loud. The solution is just to buy a smaller amplifier or apply attenuation to the output circuit.
