An armada of satellites can provide coverage over the entire planet, whereas balloons are limited to a relatively small geographical area. If you consider the cost of covering the entire planet with balloons, I highly doubt Loon is cheaper. If there's any advantage to be had by Loon, it's that they _might_ be able to better serve densely populated areas better thanks to their denser cell coverage, and that they are able to provide service over regular 4G signals rather than requiring specially designed (and slightly bulkier) radio equipment.
