I would advise against taking ISP advice from Cammy as he has next to no broadband technical knowledge and is sticking his oar in simply because he doesn't like my politics in the Free Chat forum.
I would advise not make a choice of a provider based on some dude you don't know not liking another dude you don't know. 
The trick is to decipher the technical from the pincer movement of fans and foes of ISPs. This can probably be best achieved by noting reports and trends in the ISP individual forums and balancing that against their overall customer numbers.
Now that's just untrue. Next to no BB technical knowledge? Depends on the subject. I tend to avoid the questions I can't answer, or the ones I have answered repeatedly over the years. People should use the search function for starters to save themselves the bother of asking.
I was having a tounge in cheek post, nothing more. Your politics in FC is, as best, fantasy. Let's be honest. I said nothing of your abilities with regards BB.
With regards ISPs, I recommend Plusnet because my experiences of them are generally fine. Occasionally there's a niggle, but that's life. You don't see me wading through non-Plusnet ISP forum sections flaming or trolling, unlike other members. That's because I'm not a fanboy, nor a flamer.
I disagree on the trends aspect as the forums are there for tales of woe. Rarely do people turn up and sing the praises of the ISP. Some moan about their ISP for months, which does nothing for the opinion basis. One has to balance the context of the problem (is the user a newbie / are they moaning a lot), against the problem itself, gauge the reaction from ISP support, if at all, and throw in the price to realise value.
Customer numbers are no way of making the judgement either. That's a BT way of getting customers. If all the little ISPs were worse because they are smaller, we would have a monopoly and everyone would be happy (

).
