Helol,
Well for safety, comfort and a window seat then it has to be Swiss
Statistically the safest airliner in the skies, an A340-300 ZRH/JNB/ZRH, a modestly sized long-haul airliner with the safety of 4 engines and in 2-4-2 config in economy so only a maximum of one person to climb over to/from your window seat.
