Primarily the ability to load data straight from Mongo DB without writing any APIs. Don't get me wrong, you can certainly implement the same things with other tools, but Meteor already bundles a lot of building. We pretty much "watch" live data on the server and display it as it comes. Front end JS helps us do calculations and apply labels as we see fit. The best part, we just change the front end and Meteor takes care of watching and updating the data.
