TalkTalk I'd be fairly sure would be the worst of the lot, as traditionally they have the lowest "budgetted" capacity per user.
Sky basically only push their 40Mbps FTTC service. For a long time 80Mbps wasn't even on their website, and you still can't order it online. There is more than one way to skin a cat

. Their 76Mbps FTTC is about £30pm. Over a year, that's a lot to pay to cater for Apple releases

.
BT, I haven't checked their forums, nor either of the other two. Have you yet? You can't compare three companies by only asking about the one you are interested in.
