Each Heathrow terminal is so different from the others, it's really like four different airports that happen to share runways. Terminal 2 (used by all the Star Alliance airlines) is by far my favourite of all the international airports I've been through - outbound security is usually very efficient (this is not fast track, the normal lanes) and the e-passport gates generally have very short queues, unfortunately the non-EU passport control does look like it's somewhat slower though.
