Which is Better...... 737 or Airbus A320 in Airline Aviation Forum Posted Thursday at 01:04 PM looking under the hood I would take a 320 over a 737 any day. The systems integration on the 737 is a mess of old and really old technology and now they are attempting to ADD new technology. Sure it's a workhorse but it no longer tried and true. Its a mess. the 320 is designed with the systems integration at the forefront and it works. It IS now the tried and true.
