After being primarily a Cisco user for many years, I find the switch to Juniper refreshing. The CLI is intuitive and I appreciate the hierarchy of the various configuration groups to be much more organized. I also think it is better with regard to config checking, and ensuring that the items entered into the config work with the rest of the config. For example if you happen to forget a line in a policy, or make an error in referencing a particular object, it will not let you commit the config. I know there are pros and cons of both configs, but once you get used to Juniper, you can see the benefit of why they organized it the way they did.
