To answer the original question - I have used both and also RCN. I find that Verizon with FIOS is awsome. Cable quality is great, internet is the best and the telephone is just fine. You can have as many lines as you want - just have to pay for them:tm I also have my cell with them and get one bill for all. You can get any feature for the phone that you may want. I have call waiting, caller ID and also a second number under my assigned line for 5 buks a month. It uses a different ring tone.
Also--and I find it very important, their tech service is excellent. It takes a bit of a wait, but they have knowledgable reps. The secret is to ask for an agent after calling their service department.
They do have to run a fiber cable to your house and convert the signal in your house and use existing cable. Installers are thorough and take the time to be sure your entire package is set up properly.. No I do not work for Verizon, just cannot be happier with verizon over Comcast & RCN.
