Hi Alma,
I don't think I've ever heard anyone rave about Qwest. I remember reading about some fraud at high levels a few years ago... I'd never do business with a company "known" to have leaders like that.
I have Cox. I have the "bundle" = Internet, phone and cable. I think for me the bundle costs $155 monthly. Up about $30 over 5 years I think. Not sure but I think they price the bundle so it makes imminent sense to opt for all 3 with Cox rather than just 2 of the 3 services and subbing one service with another provider. You'll have to look into that. Unless you don't want the expanded TV channel selection at all from any provider.
I find that I have very few interruptions in service re the cable TV. Maybe 1-2 a year. I call service and they are VERY helpful. No complaints. I think I've never had failed phone or Internet service.
