Which Airport to buy?

Which airport should i buy? nagoya or Muscat?

The best airport at the moment in my opinion is IAD. Washington has two active runways, one “only” for landing and one only for departing airplanes. Muscat have two runways too, but at the moment is one runway to share for landing “and” departing airplanes. So the total output of rewards and therefore for SP too is worse than IAD.
