Just a brief on plywood and compressed wood.

Plywood is made of actual timber log that being peel piece by piece then glued it together cross-linked with its fiber direction
Compressed wood is made of chips like chipboard or MDF board than being glued together.

Cost to cost wise, plywood material cost is more expensive than chips, as it needs to used whole timber log to process, while chips based just simply can take any particles left over.

Particle board can 'swell' if soak in water, as they made of chips, while plywood is the actual wood piece that will have less 'swelling' effect.

Nowadays it depends a lot of the source of it, as there are manufacturers using rubberwood, palm tree, even coconut tree to mix in between which make it less durable. Price wise between real forest timber log with coconut tree mixed one can be a lot, but ordinary consumer won't able to know it.

There are hundred of types of timber species, some timber can last 50 years without problem, some only can last short term only.

Price wise can de different totally, even up to 2x.

There are some plywood made of coconut and palm oil tree one as well lately which is not that lasting, but price wise is way cheaper than medium hardwood type of plywood.
