It depends on what models you use, but you can look at the energy ratings for the appliance to see how much power it uses, and for the average estimated cost of use per year sticker on it.
If it's close, I would go with the air-conditioner to cool, and it also removes some moisture as well. A dehumidifier will not cool since it only helps remove moisture in the air.
