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

I’ve had some really good sounding SS amps over the years but I’ve had several tube amps and they all sounded great .  Some better than others but I haven’t switched back to SS because in addition to sounding excellent they were minimal fuss. My last SS was a Mc Cormack DNA 125 and it was a damn good amp but my 40 watt EL34 PP amps that replaced it sound way better.  Can’t play quite as loud but I really never crank it loud so it never mattered.    To me it’s not about the topology it is more about the synergy with any given speaker.    
It’s foolish to buy a tube amp if you  have low efficiency speakers    Some of my best set ups were high efficient speakers with moderately powered tube amps
