In my career the only time certifications came up was for a B2B relationship where the customer wanted {n} people to be certified in AIX or HP-UX. There was also a B2B customer that wanted {n} people to have RHCE's for Redhat because they were using it for Oracle and the DBA's had to be trained on Oracle. But that's it really. I have never seen anyone in leadership care about it at any company I interviewed at for the purposes of hiring.

This mirrors my experience, unfortunately.

I would have loved to do an AIX or HP-UX cert to understand the system-level differences, but they were never on offer as part of what was free. I did take the Oracle Linux exam a few years back and found it uselessly specific, so maybe I didn't miss anything with those first two.

		so maybe I didn't miss anything You did not miss much in my opinion. AIX and HP-UX market share are much smaller than Linux now. There are some concepts that Linux could benefit from but that's down in the weeds. e.g. system management tools that can do very advanced configurations but also log what commands it executed in the background so it can be used to learn advanced techniques and quickly debug when something goes wrong.
