We have Vodafone FTTC, with a 200yd copper string (those at the end of the village have another 600yd to go). Changed from the once excellent Plusnet, who's service had dropped off after the BT takeover, and because we have Vodafone mobiles, so get a bit of a discount.
As to speed - well it's sold on the sync speed to the modem being 70Mbps. It may well be, but actual real world download speed varies enormously, and is never at 70Mbps. Upload is pretty constant at 14Mbps. Given the physical limitations of our location, I doubt anyone else would be better.
It's reliable, and the (Cairo based) support were very good in sorting out a known issue where the network doesn't recognise the modem at first.
I think BB is becoming a bit like petrol, in that in a given location, most BB providers will be broadly similar, as they work with the same infrastructure, so you pay the least you can, or consciously go for something from A&A as a premium solution. Having said that A&A forecast speeds for my property are in line with the sync speeds quoted by Vodafone. I could possibly improve performance by buying a dedicated copper pair. But I'd pay for data (probably) as Vodafone in unlimited. It works out at £55/month for 2TB/month FTTC and a dedicated copper pair plus the line rental. My broadband at the moment is £26/month including line rental. I cant see that, for my case, an extra £40 a month makes sense. YMMV.
