The double pane window should be more efficient in keeping heat out. However, there is also more heat transfer from the frames if they are metal rather than vinyl.

A split system air conditioner is a central air conditioning system that is "split" into two components: the air conditioner that sits outside of your home and an indoor component to move the air through duct work, such as a furnace and coil. A window unit only cools the single room it is installed in. It does not move air through ducts like a split system does. It will be more expensive to run a window AC to cool a home, but the upfront cost will be less than a central AC system.
