Such a setup includes two complex tools from two different parties plus a different C/C++ compiler toolchain per platform and platform SDKs (at least GCC, Clang (plus its Apple flavour) and MSVC). All those tools working together flawlessly at any given time is a minor miracle.

In Zig all those things are in the same toolchain install, which is a a single executable plus a bunch of cross-platform system headers and libraries, all under a single version number and trivially downloadable as a zip archive which works right after unzipping without setting up paths or running an 'installer'.
