Four engine aircrafts are also more difficult/expensive to maintain. Most pilots prefer two engines.

  I'm curious, why would a pilot working for a commercial airline care about the maintenance cost or difficulty?

    Two engines have more spare power than four engines. Single engine on twin must still be able to fly aircraft.
