The line times for EU/EEA citizens to clear passport control at LHR — using egates or otherwise — has become far more extremely variable than it used to be before the egates went in there for most EU/EEA passport users there.
I usually can do a quick visual and check of the incoming flight history and pick whichever line works for me fastest. The fastest/shortest times to get landside at LHR for someone like me is not consistently the egates, that is for sure.
