I'd be really interested to see what sort of speed and coverage you're getting on your 4G EE handsets at the moment.
Mine have been ranging from around 20 mbps - 50 mbps Download and 30 mbps - 50 mbps Upload in and around London.
Maybe you could start posting your screenshots of your speeds;
a good app to use is "Speedtest.net" which is available on most mobile operating systems.
It'd also be great to find out what you've been using that speed for? I for one have been hotspotting mine to download games and movies on my desktop computer, as it appears to be faster than my home broadband!
Here's a list of my better ones around East London:
