I have used Google for ages it worked fine but it is loaded with advertising and Comcast search is not. It also seems faster and I like the results better. It was one of those changes that took some getting used to but not all that tough.
It may be one of the other listed search engines with a Comcast label (I did not notice credit being given to anyone), if so you can put my vote on that search engine
