I've really appreciated the incremental builds with zig - I really like having a single static binary, and I have an application which uses a few different libraries like SQLite and luau and it compiles at nearly Go speeds.

That said, there are definitely still bugs to their self hosted compiler. For example, for SQLite I have to use llvm - https://github.com/vrischmann/zig-sqlite/issues/195 - which kinda sucks.
