The majorty of the people people I know that have had FTTC, which is very few to be honest, have not had any problems with connectivity, but I don't any of them are getting the speed they thought they should get.
FTTC is not all it's cracked up to be considering how much extra some people pay compared to ADSL.
Ok if you got a 1-2 Megabit ADSL connection and FTTC giver you 20Mb/s or more, then it may be worth the extra. i still know many people who have no interest in going for FTTC, even some that got pretty slow ADSL speeds.
