BE still have their excellent customer service, but now they have been bought out by Sky I am not sure how long that will last.
Similarly, they still let you control your line details such as SNR and interleaving, but as they become part of a bigger ISP that freedom may well disappear as well. (Pure hypothesis, no facts or special knowledge here.)
There seem to have been more complaints than there used to be on the BE forums as well; that might be mainly due to issues with migrating their network.
So, if a move might well work well for a bit, but you might find you want another move before too long.
