2 * 3 Ah = 6 Ah
6 Ah > 5 Ah

Plus with the two, one can be on the charger while the other is in use. 20V 3 Ah could charge very quickly depending on the charger and battery or really slow too. Remember do not charge a battery while it is hot from use unless your charger senses battery temp and manages all that.
