Would be cool if it could compare them.

you can scrape anything you want as long as you have the knowledge or resources.

however, im not sure if there is anything available currently that does that. Just write your own script, or write your own scraper program. If you dont know how to code, learn.. Some of the best tools you can have are the tools you build that are non-public. Once a tool goes public, the less effective it `possibly` could be.
