As a rule of thumb, I find Zig projects often come across as higher quality than many C, C++, or Rust counterparts — it’s a surprisingly strong community. That said, I don’t write much in Zig myself, haven’t explored the projects you linked in detail, and wasn’t even considering Zig alternatives as I needed something for my C++ and Rust projects.

From a first glance, they seem to be tackling a slightly different problem: focusing on efficient handling of nested parallelism. Fork Union doesn’t support nested parallelism at all.

I think Ada is great with its builtin constructs for concurrency. It helps you avoid data races, too. You can formally verify your code as well if you so wish. Ada may be too "serious" for people. :D
