My experience with BT for 7 weeks now (after switching from Talk Talk) is that their broadband service is significantly faster and it costs less.
Late April 2012 my broadband went down. In total it was down for about 2 weeks. Talk Talk sent me 3 new routers and would only refer to first line (UK) support after I had insisted (very firmly!) after 10 days with no broadband. Talk Talk India were still blaming my router. The TT UK engineer phoned and ran a simple remote test which confirmed that the fault was with their servers. Service was restored the following day. During this fiasco I received a letter from Talk Talk advising that my service charge was to increase from £20/month to £25/month from May. Time for a MAC code methinks after 6 years with Tiscali (now Talk Talk).
I live in the sticks on standard ADSL miles from exchange. My average speed with Talk Talk was 0.5 mps - hardly usable. With BT it averages 2.5 mps and now I can watch youtube and iplayer. Hardly startling speeds but 2.2 is a heck of a lot better than 0.5, believe me!
I started with BT 10GB/mnth £13 package and that clearly was not going to be enough even with my fairly light usage. For those that doubt BT's usage stats, try downloading Networx (free) to check them - maybe you will be surprised how much you use.
I upgraded to unlimited Broadband for £20/month and am now back to the capacity I had with Talk Talk but with 3 or 4 times the speed so I am happy. BTW, line rental is extra as it was with TT.
I also like the free BTFon and BTOpenzone wireless services which Talk Talk didn't have.
Until it goes wrong I won't know what BT's support is like but I like the fact that they own and maintain my line!
So far so good with BT. Homehub3 router seems to be good kit (free with package) and has strong wireless signal.
So my ratings are average for support issues, because unknown as of now. Speed reflects what is available physically to me.
Bottom line, so far BT is delivering what it said it would.
