It looks to be a less complete solution, since it only relies on the LLVM C API which is incomplete. llvmlite digs into the C++ API as well, so while it has more work to do to keep up with changes in LLVM, it's more more feature-complete
The LLVM-C API is quite powerful, and I'm planning to upstream some patch to expose additional stuff.
On the other hand, llvmlite doesn't even parse existing IR, it's basically write-only. Plus, representing the IR in Python makes it less memory efficient than using the native representation.
