Which mobile carrier do you use?

I've tried a few. I was recommended O2 when I first moved here. Fell for giffgaff marketing (unlimited internet but the internet is so slow that it's pointless) tried EE and they are terrible. Using O2 contract now and getting 30mbps downloads. Very nice. Wondered if they are truly the best carrier in the UK?
