Most .NET devs (myself included) really enjoy the Visual Studio Environment. So, if you prefer a text editor like vim, it may not be the right tool for you. The debugger is hard to beat (as Jeff mentions). C# has kept up with most features (LINQ, dynamic, async/await, etc) that are available in Ruby, and the CLR is quite fast. The core libs are also very solid. ASP.NET MVC is very comparable to Rails. There are a bunch of downsides as well, but they are well-covered by OP.
