A "module system" should be something beyond a name spacing scheme. So that's the difference.

Re: strings I had a stronger idea of that initially but I wasn't sure, so I kept postponing it, and due to features I added later it's now possible to make strings in userland... probably. I still need to think about this a lot.

But I agree that I should revisit this comparison to make it more up to date. For example an important difference would be that Zig adds quite a bit of UB on top of C, whereas C3 removes UB compared to C.

There are minor things Zig doesn't have like: substructs (I think!), trailing macros (allowing easy "scoping" macros, limited operator overloading (allowing for example userland lists use foreach), type methods are possible to extend by other modules. Then the whole way to do generic types and functions are different, with Zig building it on top of parameterized structs, whereas C3 uses parameterized modules, which creates a bit of difference.
