Most commercial applications use some sort of cage-fan, a centrifugal form of blower - anywhere you need 'forced' air with some decent pressure behind it, you'll find a cage fan. air hockey, home hvac furnace applications, bouncy castles, 'air movers' are all high-ish pressure blowers axial bladed fans can move a lot of air, but not with as much pressure....and as cheeze points out - larger fans can run slower and make less noise.

. It depends on the application. Provide more details about what you are wanting to do.

well, for axial fans, having larger blades moves more air and is much much quieter. I am not sure if it makes it more efficient, but I have heard that it does.
