Good post Duncan and thanks for the link - the issue with Quantcast is simple. If everyone doesn't Quantify their sites, then the comparisons will always be off. It's why I removed it from CN.
You could also list Neilsen netratings as well. I would put Nielsen, Hitwise and Comscore is a completely different league than Quantcast/Compete/Alexa.

Minor correction: comScore has a $610 million market cap, not billion.
