Pros
Pro Results are sorted in a meaningful way
Content is rated, and the best content is displayed first making it quick to find whatever you're looking for. As a side-advantage, for products you aren't familiar with you can usually click on the first few links and get good results instead of having to dig through multiple pages of results.
Cons
Con Content quality and layout varies source-to-source
While searching for comparisons, you will almost always get different sites in the search results. While variety is good, it makes comparing products very difficult as each website has their own tests and results don't always line up. Also, when making a direct side-by-side comparison it is harder as the information might be in different spots making it more time consuming than just using a single site (where information is typically laid out in a similar fashion).
