It costs more, but there is good lighting. They also have lots of glare. Well shielded wall packs can be excellent light sources, but one must be sure of what one is buying. Some wall packs have good light control, some nearly none. Poorly designed or installed flood lights don't provide good light either.
Flood lights can be good, as they often have good light control.
But they must be well designed and installed to take advantage of their pluses. We have all seen many examples of such bad lighting at night. A much better light is a well shielded fixture like this example. The light is directed downward where it is needed. There is lots of light and little or no glare and no sharp, deep shadows.
