Switched to BT due to quality issue when Pipex brought out ISP Freedom2Surf. I can't say I have had any issues with them, they only once contact me when I transgressed the then 100gb fair usage limit, now consuming 300gb+.

Always find that the usual renegotiation at contract renewal time gets the cost reduced by at least 25% and a new Home Hub if one has been released since the last time I renewed.

Without any issues to resolve I can not criticise the service. I am based in a village with a local exchange which means I have standard ADSL (6-7 mb/s) so speed is subjective works for me.
