For real-time systems, QNX should be compared to FreeRTOS, CMSIS/RTX, VxWorks, or, if you after the new cool stuff, Zephyr, perhaps, but not Linux.

I disagree. Linux merged the real time stuff (https://news.ycombinator.com/item?id=41594862) not so long ago so it's now a real-time capable kernel, and hence it should be held comparable to other real time kernels.
