While it is a little while until we actually start building we are in the planning stage. When I lived in Chattanooga, TN and Florence, AL I noticed that almost all basements were cement block constructed basements. When I moved to Atlanta I noticed that almost all new construciton (http://www.basementsystems.com/basement_waterproofing/foundation_waterproofing.php) basements were poured concrete basements. What are the advantages of each and which holds up better over time? What are your recommendations?

It depends on the quality of new construction (http://www.basementsystems.com/basement_waterproofing/foundation_waterproofing.php), the backfill, and the drainage. Cinderblock can be a fine material, however, it requires careful attention to waterproofing, foundation drainage and backfill, and rebar reinforcement. It will always be more porous than a poured concrete foundation.
In general, all things being equal, you will pay substantially more for a poured foundation, but if it is done correctly (same things as are necessary for a block wall) it will generally outlast a cinderblock foundation, remain less permeable to moisture, and add to the resale value of the home.
Also, these days, laborers are getting away from cinderblocks. It tends to be quicker to use the quick forms and pour versus stacking, mortaring, cutting and reinforcing block. Time is money.
