If you're comfortable with 2013, then 2014 isn't going to 'feel' that much different. Like most Inventor updates, the only significant changes are some new features and new add-on functions, but the basic 95% is more or less exactly the same as the previous version. Like Calvin mentioned above, you do want to be aware of whether or not those who you work with frequently are on 2013 or 2014, since the files aren't backwards compatible.
