I only know of one person who believes that tube watts are greater than S.S. watts and he is wrong. Read the post by Atma-sphere and take it as gospel.
Tube vs. Solid State Amplifiers
I found this really good link regarding the differences:

I've heard some (who are much more knowledgeable than me) say that a tube amp and solid state amp which are rated at the same output power in practice will not drive a speaker to the same level, that in selecting amplifier power levels, you would get similar results from lower powered tube amps.
I thought it would be interesting to see what those who know much more about this subject would contribute to this discussion.
