Actually, you can see the difference between the two versions from the download page of eclipse.
The first version is Eclipse IDE for Java EE Developers, which is mainly used to develop Java Enterprise Edition and Web projects, and of course, you can develop basic Java projects.
The second version is eclipse Classic, which is a classic version of Eclipse. It only includes Java development tools and plug-in development tools, that is, Web projects cannot be developed.
the first one is recommended, because the first one includes all the functions of the second one, as well as more advanced Java EE development and Web development functions.
