O2 are shutting the network down in my area late this month to "upgrade" it.
Complete shutdown, got an email and sms to warn me.
So will be interesting to see what this "upgrade" entails.
I still have my three sim as three are sort of like how VM manage their congestion, they find it cheaper to pay customers to stay with them instead of upgrading their network. I effectively have three free now as compensation for the performance.
Three I have so far from bit of testing while travelling found it consistently quite good in any out of city area, but slow in every city I have been in. But never excellent.
