Issue
It seems to me these two views are virtually identical, especially since Galileo. Is this true, or am I missing out on some features of one or the other?
Solution
According to the Eclipse help, the Project Explorer
provides a hierarchical view of the artifacts in the Workbench, which is customized by the specific configuration of your Workbench.
With only the Java Developer Tools (JDT) installed, Project Explorer nearly looks and behaves same for Java Projects as the Package Explorer (including refactoring and other source code operations in the Context Menu). But Project Explorer is usable for other languages and project types as well.
Additional plugins contributes "extra information" to the Project Explorer view making it much more "sophisticated".
For example: if you have Dynamic Web Project and web tools installed, Project Explorer shows you additional tree nodes like Deployment Descriptor & JavaScript Resources. You can see (and configure) all available contributions in Project Explorer / Customize View... / Content. If you use SpringSource Tool Suite 2.1.0, have additional nodes for web projects, spring beans and web services.
