Quinny: Moved from TCL cable a year ago and was on 130/20 down 150gig cap I think it was. Moved to 30/10 UFB unlimited (no longer available). Have totally not looked back. Speeds fantastic we game, youtube, stream and download with zero issues. I have never had to do a modem reset when the TCL one needed all the time. Do miss the tv side as in some ways was better that sky direct which now have.
The point you make about Sky is probably the only thing holding me back.
TCL/Voda's package pricing is quite compelling. I pay ~$150 now for Sky (Sport, HD, MySky) and 100/100 Unlimited Cable. The cost if I switch will be significantly more.
