Software to Make a Comparitive Analysis with Other Sites
 

I'm wonderig if anyone is aware of a site or software tool that allows me to make a quality comparitive analysis of my site and other sites that rank well under a certain keyword phrase in Google?

I'd like to compare backlinks, numbers of pages of content, overall size of site, etc... Basically I want to see where I can gain competitive advantage. Thanks.
