experienced pilots aren' t obviously excellent. Most are good or excellent,
I' ve seen some very bad. FO or Capt. As well some young FOs are excellent and will detect the aircraft, would it be Airbus or Boeing, should not be flying there in daylight IMC. And yes, the A321 is a powerful aircraft which will clear a hill. If the pilot orders it.
Experience alone is not everything. Initial training and recurrent training is very important. Could be very good, inexistant or a joke. Depends where you fly or have flown. But does not depend on A or B!
