Julia is generally in the same ballpark as Numba (depending on the application they should be within 2%). The difference is that Julia is a full language, while Numba breaks if you try to use it with anything else.

Yeah, Numba usually delivers on its performance promises when used right, but can be such a huge hassle oftentimes as to make it not really worth it.

Yes, Numba is just barely less awful than managing a C build process.

Julia is a much better solution to the two language problem, here's hoping it can overcome the ecosystem inertia.
