The difference would be too small to worry about IMHO but I think the generator would burn more fuel. But, again, it's statistically insignificant if you want to be comfortable.
My approach is use the dash air most of the time. By opening a rear roof vent a small amount you can pull a bunch of cold air back from the cab. If it's really hot, turn on the generator and run them both.
In all honestly, I'd rather burn a little more fuel to keep everyone comfortable.
