Great article. I have recently been looking at the state of Clang on Windows, though not so much from a performance perspective.

> Microsoft have announced that a full integration of Clang into the MSBuild framework will be coming soon. Let's hope that they will deliver on this promise.

This has been made available on Visual Studio 2019 version 16.2. It is very easy to use in msbuild-based environments (or cmake->msbuild). See https://devblogs.microsoft.com/cppblog/clang-llvm-support-fo...

I expect llvm/clang to dominate over the long term (10 years from now)
