Comcast vs. Qwest

[Ender]

Qwest just installed new fiber optic service in my neighborhood and they are going door to door offering service. I was quoted at $80/month for the first 6 months, and $100 after that for 20 MB internet service and HD standard cable. They flat out told me though that I could just keep it at 80 as long as I called in every 6 months and requested the promotional package.

I currently have Comcast cable service for both TV cable and internet and pay about $140/month, which I think is bullshit and I have known that I need to do something about that overpricing for a while. I think my internet service speed is currently 12 MB or so.

I have heard Qwest internet is much slower than cable, but maybe that was when comparing DSL to cable? If I would be getting 20 MB rated internet service through Qwest fiber optic, do you think it would be faster than my current 12 MB cable service through Comcast?
