This model is more expensive than the basic version for several reasons. It includes four windows instead of two, it has airflow events instead of none, it has extra gear pockets and a gear loft, and it has a nicer cinch and strap carrying bag. The weight of the canvas on the roof, walls, and the polyvinyl floor are identical. The poles that are included are also identical between the two tents. It basically boils down to more ventilation.
