Somethings that's going to impress you down the line with C# debugging are using parallel stack views to debug multi threaded apps (without this could be significantly harder), remote debugging (sometimes you simply can't debug your application due to practical issues like may be your app interfaces with an expensive or impossible to deploy in your dev machine to debug with it), the watch feature in the debugger that allows you to debug complex linq queries and even expression trees on the fly and debugging external assemblies by attaching debuggers. VS is heavy on resources, but it delivers value unlike a gazillion of JS apps.
