Yes he would. The point of the overall stats are to have A2G pilots compete with A2A pilots, where a typical A2G sortie will give the same as a typical A2A sortie. Right now it looks quite balanced to me. Look at this example, which is quite representative for the 51st Stats:
<51>Teknetinium has 112 Hrs and 6270p on A2A alone
3Sqn_Cali has 109 Hrs and 10374p on A2G alone
It seems to me that A2G pilots does NOT have an tougher time, and even might have an easier time racking up points per hour... Ofc, all this is dependent that you finish your sorties and not get crashed, as this will make your point go down.
