Three phase will use less current, but most residential homes are single phase only. It costs quite a bit of money to have the electric company run three phase service to your house. That would not economical just to be able to run a three phase system.

Adding to what Dr1757 said, I think energy consumption will be about the same in either case. Ultimately it will come down to the SEER rating of the unit.
