IIRC Tru64 or OSF/1 (nee Ultrix) was a mainstream Unix based on a microkernel.
The problem with microkernels is their advantages (in terms of, a component of the kernel crashing won't take down the box) has rarely been worth it in light of the disadvantages (all that message passing hurts performance). So "better" depends on your POV.
