Is crawl space or slab better?

Slabs resist moisture but crack more easily when soil shifts. Crawl spaces work better on sloped properties but cost more. Slabs provide more durability, while crawl spaces hold up better in earthquake- and flood-prone areas.

Which is better vented or unvented crawl space?

Unvented. The principal perceived advantage of a vented crawl space over an unvented one is that venting may limit radon and moisture-related decay hazards by diluting the crawl space air. Additionally, providing a vented crawl space may make sense in flood-prone areas such as coastal zones subject to hurricanes.
