This sounds like an entirely localised issue and is not a reflection of the network on a national level. (although there is no context provided as this is your only post on these forums, we would be happy to try and help figure out the cause of your issues)
I can say as a previous customer of the other network you've mentioned above, my experience on EE has been considerably better (both from a network performance and a customer care POV) in multiple towns and cities. Previous network had many of the problems you've stated above, but I understood why that was and I was willing to move to get myself a better service after testing the connection in my area.
There are absolutely areas where the EE network is not as good as another, but the same could be said for any other network. If there was one network that was perfect everywhere, we would all be on it.
Your experience is your experience and the above is mine. Networks differ.
In future try to avoid making such blanket statements without context, or preface your comments with the issues you've encountered in your area.
