I think it's the best IDE nowadays for game development, mainly in Unreal, but it's also the best one in cost/benefit for Unity. It might not work for people who prefer a more lightweight IDE, it's still pretty heavy and its indexing takes around 2~3GB of ram, but it's worth the quick indexing and IntelliSense.
If you're doing any sort of text editing, you should consider Vim--once you climb the learning curve, you'll be faster and more efficient at everything you do. Also, Vim is my default search/replace tool--whenever I need to make changes throughout a document, most often, I'll copy and paste into a Vim window so that I can take advantage of regexp-based replacements. Vim isn't for the faint of heart, though--it's hard to learn and super complex. If you use a text editor once or twice a month, or just need a simple way to strip out formatting, Notepad will get you where you want to go without all the confusion.
Helps you refactor your code into more readable and more efficient code.
Highly customizable UI, including color themes, shortcut key remappings, and the ability to put any Window, Toolbar, or Docked tab anywhere you want, even on second screens. Additionally, this functionality can be customized per project, not just globally for the whole machine.
More control over Git. Visual Studio just has the basics, but mostly all that is needed is for git repositories. It gets the job done., but Rider takes it one step further and gives you most of what you can do on the command line's simple, easy to access menu options.
If you use TeamCity, then you have complete and full integration into your TeamCity build server!
You can double tap your control key and get a quick pop up to instantly run any command. Double tap shift and you can search your entire project, filenames, AND text and filter that search!
It's easy to learn while still advanced. It has smart tricks up it's sleeve that you have to find out but that is to be expected. It has a modern new UI that some will find too compact, but it took me just a day to like it more than to switch back.
I don't consider the steep learning curve to be a hinderance on the overall usability. I would rate this a ten, but to be honest a lot of people do get hung up at the beginning and just abandon it. However, for people who have made the moderate effort to get over the hump, nothing can be more usable.
The support forums and knowledge base are extensive and the JetBrains support staff respond quickly to new posts and help resolve issues. There is also a publicly accessible issue tracking system, which allows you to stay on top of any bug fixes or enhancement requests.
The support is somewhat lacking; Vim doesn't really have support outside of its forums. The forums, while notably good, aren't equal to real support though, and the steep learning curve makes you wish there was a help desk that would assist with all of the basic questions. There are several handy books and guides that can be found, and most implementations of the product come with "vitutor" which walks you through its usage.
It’s a great free tool but not as enhanced as IntelliJ platform that JetBrains Rider has. Debugging and access to database is not as comfortable to use. Sure, you can save money on IDE, but may need to spend it on sleeping and stress relief pills.
I think it comes down to usability (and frankly, just preference). There's an old adage that Emacs is a good Operating System with a poor Text Editor! Jokes aside, when looking at different text editors, such as Emacs or Nano, Vim is the one that is usually always preferred because of how simple it is to learn. The learning curve of Vim compared to other text editors just makes it such a natural choice.
