Optimum Online with the Boost option is overwhelmingly superior to Road Runner. The bandwidth difference is obvious. With Road Runner my web browser would lag significantly while a file was being download from one of my websites. On Optimum, with several files being downloaded I am able to surf with unnoticeable lab. It is quite refreshing, and it has opened the opportunity to host more files, and offer more bandwidth.
I have successfully transferred my server from a Time Warner internet connection to a Cable Vision connection. Cable Vision’s Optimum online is relatively painless to setup. With a standard internet connection you will have to add the available Boost service to get port 80 and port 25 open. You are actually able to configure this by logging into the Optimum Online website. Apparently the dynamic IP of Optimum is comparable to that of Road Runner; it doesn’t change very often, which is a requirement of a reliable server environment.
As per Time Warners commercial they claim to currently utilize fiber optic technology. I can only speak from experience. Time Warner Road Runner is extremely fast for practical applications. I can download at approximately 1.2 Megabytes per second, which is relatively fast. I do not know the exact download speed of Fios, but frankly I don’t like it, at all, that either of the companies do not explicitly state DOWNLOAD SPEEDS. They say, “we offer internet service”, or “broadband service”, but what the heck is the download speed? When I go into a car dealership I know how much horsepower and torque I can getting for my money, but Time Warner and Verizon make it a scavenger hunt to track down pertinent information.
Overall, for the basic home user, you will see zero difference between the performance of Verizon Fios versus Time Warner Road Runner. Although if Fios does indeed have a greater download speed, then this will come in handly when downloading Linux ISOs that are typically 600 or 700 Megatytes. And the DVD ISOs that are a couple of Gigabytes. When downloading ISOs of this size you really need some bandwidth otherwise the download time is up in the stratosphere. 
Also, probably the most important, and pertinent piece of information is PORT BLOCKING. Time Warner does not block any of the inportant server ports, but I have heard rumors that Verizon Fios blocks the almighty port 80 and possibly others
