DSS Certification Exams for CATIA, ENOVIA, DELMIA

I'm considering taking DSS exams for CATIA and noticed the exams for ENOVIA and DELMIA.

My question is this:  Of all the exams in the image below, what would be of most value to an employer?

I'm guessing that ENOVIA and DELMIA exams are niche skills compared to CATIA Part Design, Surface, and Assembly exams.....is this correct?


Thanks for any feedback....and hopes for a great weekend to all.
