My E Gate experience has generally been ok at LHR but I don’t use it much. The airport I use most coming into UK is a disaster, as Manchester E Gates just don’t like my paperwork as stopped 90% of the time. It’s a bit irritating if you have come of an A380 get down the long walk ahead of the crowds only to be delayed at immigration, and even worse if you bump into inbound from the subcontinent as happens occasionally. Anyway all a bit first world but irritating.
