That's a bit too much of a blanket statement. Latex isn't special. Everyone I know has used it, 100% of them have struggled with margins and fonts and images and equations needing to be rewritten three times and so on. I would not find a Latex resume even remotely novel or interesting. I certainly wouldn't downplay it, but Latex isn't instant-streetcred either.

Yeah. Using it for your CV is a costly signal that you’re the kind of academic type who writes enough math to only find LaTeX comfortable.

If writing math is not what the job that you’re applying to is looking for in you, you should probably only use LaTeX for your own enjoyment.
