Well - this is a little late to your quesiton, but I am in Butler and have Armstrong. Decent. But not anywhere near as nice (television lineup-wise or HSI-wise) as the FiOS I had when I lived down in Shaler.
Not even as nice as the Comcast that I had before FiOS.
But Armstrong definitely has better customer service than either of the two. Service calls due to outages or problems generally occur the same day, and never with any kind of service charge.
