Ask HN: Ryzen or i7 for Visual Studio C# and JS development?

I'm building my next dev rig and wondering what processor is better for C# & JS development in Visual Studio. I can't find any trustworthy benchmarks, only some that relate to C++ compilation. I'm trying to decide whether to get i7 7700k or Ryzen 7, but don't know if Ryzen's higher core count will provide faster build speeds in C# compiler and gulp than faster single-core speeds and lower core count in i7. Can anyone share their experience?
