Iron provides a bare minimum of concepts that you need. Rocket comes with its opinions and a lot of features nicely integrated. Iron will allow you to design anything you want easily, because all elements are as simple as they possibly can be and compose nicely, but requires that you have your own vision and enough experience to know what you need and how to build it. So Iron is great if you need thin layer of web interface added to some existing non-web project, or have enough experience with web and Rust to have own vision. It also work fine with stable. Rocket is great for all other cases - if you are new to webdevelopment and/or Rust, expect framework to tell you how to do things and don't mind using unstable. I don't have examples of sites, but none of those frameworks deals with UI, so I am not sure how would that help you.
