I personally use Rider daily instead of Visual Studio Enterprise when I am working on our back end web API that is written in ASP.Net Core. I've also started using Rider instead of Visual Studio for our deployment and upgrade applications, and all the utilities that we write to deploy our applications into Azure and AWS. Since I prefer to use Linux as my desktop, instead of Windows, it was an easy choice to start using Rider. However, after using it, I am now hooked on it and also use it on my Windows desktop when I need to work with Windows applications.
If you've ever used Resharper in Visual Studio, you will find that the refactorings and code suggestions that it gives you are very well thought out, make your code cleaner and easier to read, and help you write better code. The only problem with this is that it can sometimes negatively affect the performance of Visual Studio, sometimes so much that you have to turn it off if it's a very large project. Rider gives you back those nice refactorings without the performance hit.
It's smooth, works well, is highly stable, and gets out of my way.
