I work for Time Warner - as a NE - Thorne can attest to it.
I am not biased - In fact in most cases I hate what we (TWC) has to offer our customers as far as pricing is concerned. I think it is over priced, etc.. I also think when you are the largest company in the area - you will obviously have more complaints.
TWC - We will launch 30/3 and 50/5 here soon in select areas in Columbus. I would say most people who have an issue with TWC Service - is not because of our IP Transit, it is because of our HFC Plant. While this may or may not lower the price on our current tiers (I would go with not).
U-Verse - great if you live close to the DSLAM, but the whole "You get your own line" is crap. You "get your own line" because U-Verse is VDSL, still using Twisted Pair Phone Line, period. Your bandwidth is shared from the DSLAM Northbound. That would be like me saying "You have your own Cable Drop".
While I will always say - U-Verse has the best delivery method (all IP). Their choice of using VDSL and Twisted Pair was poor. Had they invested the money they could have really been leading the way everywhere they deployed U-Verse.
Insight - TWC Manages their CMTS's as far as IP Connectivity - that is it. Insight manages their own plant, they also schedule their own node breakouts/splits. They also tell us what services to enable/disable and when.
WOW - Like Joe mentioned WOW seems to price really high if you don't bundle. I don't agree with this, but every other MSO does the same thing, so I can't blame them. I have used their Internet piece before and it has always seemed to work just fine. My only knock on WOW (same as Insight) was the Advertisements in the On-Screen Guide. I have also heard WOW has a low number of HD Channels (I could be wrong about this).
In the end for what you are looking for - Anything at 7Mbps and over will do you just fine. If you are just using it to do streaming Netflix - then you won't need much more than that. I can never think of a time I have pulled more than 3Mbps from Netflix.
