Heathrow terminal 5 (almost exclusively BA/OneWorld) is on average the nicest hub terminal I've regularly been to. It's busy but once you've explored you'll know the quiet corners. Buses to the aircraft are rare. Security seems busy but fast. Baggage is a decent walk but I'm almost always connecting so don't need to go there. A London underground station going directly into the middle of the city. Food expensive but not Schipol or Frankfurt expensive (£4-5 for a decent sandwich instead of €10).
