Yeah, that was basically it. Comcast had higher service availability than Duquesne Light for their respective products and since both are typically used together I gave Comcast the bonus.

I suppose awarding them a bonus based on a comparison to a different class of product is unfair. The below list is restricted to residential ISP services I have used ranked in order of preference:

1. Verizon FiOS - 300/300Mbps
2. Comcast Xfinity - 10/100 Mbps

Xfinity is showing gigabit options in the Pittsburgh area now, so it appears they've upgraded their network since I last pondered their offer page.
