My personal ads are all image ads through the content network. I've had some issues with non-relevant sites but the great thing about the report is that it makes it super simple for me to exclude those sites now.
I pulled a report for a client who uses text ads on the content network and I was really impressed with the relevancy for the distribution for his ads. Relevancy was much better for his than mine but we have two totally different industries and ad formats.
