Cable Vs. HighSpeedPhone Please Help

My dad is thinking about switching to Bell Sympatico High Speed instead of Cogeco Cable.

I personally love Cable, and have only had one or two problems with it. I don’t know why I’m so terrified of High Speed Phone, so I need to know if it’s worth *****ing at him about.

They’d both be unlimited usage and bandwidth. That I’m pretty sure of. The rest I don’t know.

Is the speed difference worth it?

Please help, thanks in advance.
