Rider is a full-fledged, cross-platform C# IDE on par with Visual Studio (full version, not code). I have used a little bit of Rider and other Jetbrains products. It was some time ago, so take it with a grain of salt. On my windows machine Rider felt a bit snappier. Debugging was also great. Pretty much the same as Visual Studio. Code completion, code navigation and refactoring is at least on par if not greater with that in Visual Studio. Git integration is there, file-explorer is there. Haven't used WPF/XAML so don't know about that. Generally speaking if you buy the license for all Jetbrains' products to use WebStorm or other stuff they offer I think it is worth it. Or maybe you would want to develop C# apps on mac or linux then Rider is the go to. Other than that I wouldn't bother buying the license.
