You do what makes you feel most comfortable about.
For the record, the air would need to be regulated to not blow apart any fittings, and I would open closest faucet in line first as I progress through the entire system.
For me, 2 gallons and using the water pump and service line provided is easiest.

Most decent air compressors have a regulator and most folks that have an air compressor are smart enough to know how to regulate the pressure.
I always blow the system out even if I am going to use antifreeze.
