Pings should always be lower via fiber.
Are you asking us for websites that YOU can compare or are you asking US to compare fiber pings to Comcast HSI ?
What's the logic in that? The latency really comes from the processing time at each hop/router/media converter/whatever, not the time spent in the cable. Signals go thru copper at near the speed of light anyways.
To the OP: I would say go with whoever can get you the best price for whatever service you need. You will probably be better off with the local provider than a big one like Verizon, but thats just my 2c.
