I have the Virgin 50/5 cable service and am very happy with it.
OK, I pay well over the standard rate (£44.99 a month - ~$70 USD) but I get a genuine 48Mbit/s down and 4.5Mbit/s up. I've found their technical support to be excellent and when I used to play WoW I'd have a consistent 30-40ms latency. I run my home office via a Cisco IPSec VPN tunnel and use HD video and voice all the time with almost no issues.
When I contrast this to my BT DSL service in my old place, I was lucky to sync in at 1Mbit/s down and 500Kbit/s up. Whole weekends of sparse connectivity weren't a surprise and I got used to having to go in to the office to work on my regular "no internet" days. All over a "super fast ADSL2+ line". My experience isn't unique, anyone living in an area with ancient cables far from the exchange is stuck in this situation.
So for me at least, Virgin can take my money. It works great, I have had almost no issues and when they say 50Mbit/s I'm pretty much getting it. I'm looking at moving house next year and a genuine criteria is decent internet. Virgin cable will be a good sign for me.
