Too many categories in this competition to pick just one, and there is akways something wrong. My favorite airline in terms of aerial photography flies fifty year old aircraft with iron maiden seats. My fave airline with respect to network is not really an international airline. The most comfortable seating I ever experienced was in a wonderful aircraft type that the airline infuriatingly decided to sell, replacing it with generic shit, coz everyone else did already. Customer service is the best in an airline which is slowly dying, so I can't fly with them as much as I once could. The best airline in terms of business and hubs tends to have bdsm dominatrix types for cabin crew. The most jaw dropping ones in long haul are too expensive given that they don't fly nearby.

But really, my absolute bestest top airline is First Air, because the pilot with balls like watermelons managed not to crash into the ocean bay immediately after takeoff, when we flew into a massive windshear which reoriented and depressed the aircraft, sending it into the water. I mean, we dipped our still unretracted undercarriage. I really thought I was going to die, and look, I'm still here ;)
