Django or Rails?

I am in the process of looking for an alternative web development framework to implement at work. Currently we use ASP.NET for almost everything and I am interested into moving off of it for either Django or Rails. I know everyone and their mother has asked this type of thing but I want to specifically what types of web apps Rails is better for and what types of web apps Django is better for? Does it matter? Can I write an inventory system in Django as easily as in Rails or vice versa? My first project will be building an intranet application from the ground up with an emphasis paid time off but also with some social networking, blogging, etc. incorporated. I am leaning toward Django since I like Python better than Ruby, but Rails seems pretty kickass… what do you think?
