Tube Power vs Solid State Power


I continually hear Tube power is more powerful than Solid State Power. IE; “A 20 watt tube amp’s power is like a 60 watt Solid State Amp’s Power” and so on… Is this true ???

I always think of the “What’s Heavier, a pound of Feathers or pound of Rocks story?” A pound is a pound right ? 
Maybe someone could offer some thoughts and explain if this is true or not. 
Thanks

Would rather have the Carver crimson 350’s than the Sunfire or my very long wait monos from another company, and those 1st edition emotiva xpa-1 monos. 
350 Watts of tube power is bada$$ !!

 I remember years ago, getting any amp with 300WPC+ was always near 4K +$ or so. My first amp was a Onkyo m-504 which I paid this audio shop what I could for months and months and months, no interest, I worked at a audio shop making 90$/week, so it took me a long time for my first amp, also purchased an Onkyo dx-7500 top tier CD player demo model. 
  Used my tx-890 top o the line as a preamp. Amp lasted about 2 1/2 years before the right channel binding posts literally melted to molten plastic.
