IntelliJ IDEA vs JetBrains Rider

IDEA places an emphasis in safe refactoring, offering a variety of features to make this possible for a variety of languages.
These features include safe delete, type migration and replacing method code duplicates.

Uses a fast indexing technique to provide contextual hints (auto-completion, available object members, import suggestions).
On-the-fly code analysis to detect errors and propose refactorization.

A very complete development environment support.

IntelliJ supports many languages besides Java, some of these are: golang, Scala, Clojure, Groovy, Bash, etc.

Many plugins are available for almost any task a developer may need to cover. Plugins are developed by Jetbrains themselves or by 3rd parties through the SDK available for writing them.

IntelliJ IDEA hardly ever crashes or has any issues that plague other Java IDEs like file corruption or slowness.

IDEA has a clean, intuitive interface with some customization available (such as the Darcula theme).

The documentation is exhaustive, easy to navigate, and clearly worded.

With ability to step into a certain part of a large method invocation (Shift+F7), drop frame, executing code snippets, showing method return values, etc.

There is a free community edition (open source) and an ultimate edition, which you can compare here.

The ultimate edition is available for free for one year for students but must be registered through an .edu e-mail account.

These simplify the daily work, e.g. copy/cut a whole line without the need to select it.

Verify yourselves as a student to get more perks.

Creating an embedded database, running SQL script in a dedicated terminal, viewing tables and their contents, and creating a connection to an in-memory or embedded database is fully supported.

ReSharper is a popular Visual Studio Extension for .NET Developers. IntelliJ IDEA is a popular and fully featured JAVA IDE.

Extremely good at filling in all the mindless boilerplate type code while you stay productive.

Rider has everything you want from a serious IDE, but without the bloat. This results in significantly fast performance in day to day operations.

Project Rider supports the .NET Framework and Mono, with CoreCLR support in the works. It also includes templates for creating new projects, and when you create an empty project, it's literally empty

As well as running and debugging multiple runtimes, Project Rider itself runs on multiple platforms. It runs on Windows, Mac OS X, and Linux.

Intellij plugins for Git, Mercurial, and TFS plus Local History of files.

Project Rider can build MSBuild and XBuild solutions as well as DNX/.NET CLI projects, and allows debugging .NET and Mono applications. DNX/.NET CLI debugging and CoreCLR support are coming.

With a university email, Rider can be obtained for free.
