除了资源占用和清爽度 功能上没区别 IntelliJ 是超集
Do I need a language plugin for IntelliJ IDEA or a separate IDE?
IntelliJ IDEA Ultimate is a superset of most IntelliJ platform-based IDEs. If the bundled language plugins are enabled, it includes support for all technologies that are available within our more specific IDEs, such as PyCharm, WebStorm, PHPStorm, and so on.
So, for example, if your application's codebase is mainly in Java, but it also uses Python scripts, we recommend using IntelliJ IDEA in combination with the bundled Python plugin. If your codebase is mainly in Python, PyCharm is the right IDE for you.
