Airplanes are considered by many as the Holy Grail of UAVs. They can generally fly for a lot longer than multicopters (as they have wings and don't have to use up battery power on lift). They are much easier to fly (as they can actually glide and, if the motor cuts out, they don't drop like a rock). However, the difficulty with airplanes is takeoff and landing.
