Well, that could be countered with the fact ISD turbolasers pump out teratons and at full power can do 2.4 petatons, and the Executer could do 250 petatons at full power, and the Death Star can do 1E38Joules which is more than 100,000,000 times the power of the earths sun. Structural reinforcement and armor plating? IIRC they can regenerate 18 teratons a second (that's more than the entire Fed fleet could pump out) and they can destroy planets in less than 15 minutes. This is called BDZ.Or this:
As much as I'd like to agree with that assessment, even the wikipedia lists the SW weapons as only laser by title, not be actual weapon energy type.
SW weapons and shields to withstand such weapon attacks are likely stronger but the power requirements for them are much higher than for phasers which can do similar damage with less power. However, since ST doesn't typically generate higher power levels, they'd be left searching for weaknesses, and assimilating SW stuff to use against them.
