I would never ever use wood again, but only use Azek for a deck. It isn't totally care free, but mostly.
The joists of course have to be wood so PT is a good choice as although it won't last forever, it lasts a lot longer. It is no longer made with arsenic so is much safer. The 2xs cannot be used on the ground as they have a .25 retention, but the 4xs can, as they have a .40 retention.
