Ask HN: What is the state of eGPU on macOS?

What is the real state of eGPU on macOS?

Akito Node says it supports macOS 10.13, AMD CPU's only.

Razor Core X says it supports macOS, nVidia and AMD it seems.

I feel like Windows eGPU support is the best and I have projects where eGPU's will be used. Switch to Windows for development or is eGPU support on macOS really production ready? I have no objection to making my own tools if needs be.
