better, compare just planes
Boeing 737 vs Airbus A 319/320 ==> Airbus A 319/320
Boeing 747 vs Airbus A 340/380 ==> Airbus A 340/380 (i'll fly the B747 this summer)
Boeing 757 vs Airbus A 321 ==> Airbus A 321
Boeing 767 vs Airbus A 300 ==> Boeing 767
Boeing 777 vs Airbus A 330 ==> Boeing 777 (actually the Boeing 777 is great
, I've flown both of them so this vote counts more xD)
