Tube Watts vs. Solid State Watts - Any credence?


I've heard numerous times that Tube watts are not the same as Solid State watts when it comes to amps running speakers. For example, a 70 watt tube amp provides more power than a 140 watt solid state amp. Is there any credence to this or just sales talk and misguided listeners? If so, how could this be? One reason I ask is a lot of speakers recommend 50 - 300 watts of amplification but many stores have 35 watt tube amps or 50 watts tube amps running them. More power is usually better to run speakers, so why am I always hearing this stuff about a tube watt is greater than a solid state watt?

Compare Alan Watts to Reggie Watts, and you will find that one continues to produce sound and the other does not.
An interesting phenomena I noticed from decades of guitar amps is the tactile "snap" of tubes. Many geezers like me tried out various SS guitar amps over the years and regardless of design most of us return to the warm land of tubes (some cleaner playing jazz dudes still like Polytone amps, and bass players often prefer the extreme wattage of SS like my Class D Ampeg)…the seemingly ballsier "clean" tone (all about the aforementioned tube vs. SS harmonics) is where a lot of the mojo is revealed, as that means the underlying grease will rise to the surface. Modeling amps…meh…my hifi tube amp also "seems" to be ballsier at other than extreme levels, and those extreme levels are generally accompanied by inebriated dancing madness so they might not count.
"Tube amps have no bass" seemingly doesn't address the countless tube bass amps like the amazing Ampeg SVT that's been around since 1969…Mesa made an astonishing sounding tube head in 1983 or something that a dude in my band back then used. Also note that tube hifi watts have been proven in many scientific studies using sine waves, pink noise, grunge music, various speaker loads, various bong loads, yo mama, and luddite resistors to illustrate the fact that tube watts are more fun. My Jolida 502p sounds best using the 4 ohm tap…it's a fave. Another note about tubes…the Woodstock ('69) sound was powered by piles of McIntosh tube amps under the stage, a fact I recently discovered that makes me happy.
