I've lived and worked in most European countries and the general broadband provision in the UK is superb. Yes, there are rural locations that have shocking broadband but in general most people can get FTTC 38Mbps for about £20/month and FTTC 76Mbps for about £30/month. For those lucky enough to get FTTH you can get 900Mbps for £60/month.
I would challenge anyone to go to France, Spain, Portugal, Germany, Holland, Belgium or anywhere in Eastern Europe and get that sort of coverage for those prices.
These surveys are very interesting and great for beating up the incumbent government but they simply don't match the reality of real people living in these countries. Now, if they said Singapore or Hong Kong were better then yes, they have highly available 10GbE fibre for buttons.
