I've lived in houses with block walls and poured concrete.
Were I to build a home, it would be with poured concrete walls in the basement.
Crushed stone under the basement floor is a must.
Exterior waterproof membrane is a must.
Proper grading and adequate distance from the home's siding and the ground is a must.
The system Norton described sounds interesting.
And add my name to the list of folks who mentioned making certain the basement will have enough headroom.
When one of my buddies custom built his home, he put foam insulation under his basement floor and on the outside of his poured concrete walls. After almost thirty years, his basement is dry and warm. The insulation has not created any negative issues.
