With discipline, it is both more expressive by having a better and more powerful type system, and faster by allowing much finer control over code execution, data layout and allocations as well as offering actual GC tuning options. .NET's compiler is much more capable too, and the rate of improvement is not slowing down. It also has much richer package for writing line-of-business applications productively. The main advantage of Go used to be and still is "culture". But once you apply such minimalism mentality to C#, it gives a much better end result.
