Thinking of switching ISP from BE to Virgin Media

Zoom7000

I'm currently with BE Broadband for my Internet connection. I pay £18.26/Month for on average 10Mbps (on a good day!). In addition to this, I pay £14.60/Month to BT for standard line rental. I make no calls whatsoever using my home phone and merely use it for receiving calls and the Internet connection. So, currently in total, I pay £32.86/Month for Phone and Internet. I've been looking at alternatives, namely Virgin Media, who are much more competitve.

Virgin Media are currently offering:

60Mbps (£18.50/Month) + Telephone Line (£13.90/Month) = £32.40/Month (Discounted @ £23.15/Month for the first 6 months) and also, I get £57.57 if I order through Top Cashback.

Seems like a no brainer, however, there are a few things that have stopped me from switching so far:

Traffic Management/Shaping: Just how bad is it? I do occasionally download the odd heafty packages, ISO, movies, iTunes stuff, BBC iPlayer (HD), 4oD, Steam etc etc. sometimes all in 1 go. I've read that VM do at times throttle you down to 75% of the speed. However, right now I'm only getting nearly 10Mbps anyway, so I'm thinking it won't be all that bad if they throttle me down to 75% now and then, which is 15Mbps.

Virgin Media Super Hub: Or as it's been called, the SuperDud or PooperHub. Is it as bad as everyone makes out? Just what is wrong with it? Currently I'm using BE's Thompson TG587n v2, which isn't anything special itself.

Customer Service: Albeit based in Bulgaria, BE's support has been pretty brilliant everytime I have had to call and I've had no major issue. I used to be a VM customer at a previous address and I've dealt with my fellow Indian compatriots and at times, it has been rather annoying! However, whenever there has been a physical problem, VM have no issues sending out an engineer, whereas if I have a problem with BE, they usually say it's a BT issue that they need to fix and getting an engineer out with BT is next to impossible at times!

So, the question is, should I make the switch and get better value, or should I stick to the peace of mind of BE (~80% of the time) but not as good value.
