Spa Cabinet Material

[Lionheart_CHP]

I'll soon be ordering my new tub (Sunrise S104) and I've noticed that the cabinet comes in two different materials - "Polysteel" or "Eternalwood".  I'm not sure if these are industry standard terms or just names that Sunrise uses.  On their website, it's hard to see much difference but I believe their top line "Paragon" series only comes in Eternalwood. 

I've been leaning toward the black colored cabinet, but that color only comes in the "Polysteel" material.

Does anyone have any insight into these??  Thanks!

Anyone able to give a brief description of the two? Opinions?

   Best guess would be one is a thinner cheaper panel and the other is a thicker nicer looking one. They both look ok from what I can tell.    Cal-spa had something similar.
