Yes, quite a bit. Although I tend to use it more for my blogs, it is still very useful for submitting a sitemap for hubpages and understanding a lot of other, behind the scenes type stuff.
I like that it also shows things about keywords, impressions in search and average position in the SERPS. I use Google Analytics as well because they provide very different information and services.
If anyone doesn't already use Webmaster tools, I would strongly recommend using it. Very simple to set up as well.
