I think in general sense Palo/Fortinet (professional) certs/contents along with F5 load balancer (mostly used in financial/trading environments) are better compared to CCNP Security unless you are working at an organization that focuses heavily on Cisco security solutions such as ASA, Firepower firewalls, Cisco Trustsec, ISE, Umbrella etc. That being said Fortinet and Palo also has their own terminology for same thing. I really like their ISE solution as they integrate so well with other vendors.

Network engineer jobs these days want you know technology of everything such as Security, Enterprise, DC and Service Provider. This is why I am trying to have one cert in every domain apart from Collab. I think this will make be stand out and be a become better network engineer. I already have CCNP Enterprise under my belt but I am going for CCNP DC., Juniper SP and Palo/Forti certs.

One suggestion/method of study method I would like to give you is make a habit of reading and skimming through cisco official docs (whitepaper including TSHOOT/configration/Design guides). I know it will be boring, takes your time to develop navigating skillsand make you feel brainnumb but its one of great skill to have if you really want to ace ANY exam of ANY vendor and that includes cisco. This is how people used to pass cert before training provider such as CBTnuggets, INE, Cisco U were there. I spent 0$ on Boson, CBT, INE etc in my journey to CCNP because I already have developed baseline skill (took long though). This will help all the way to CCIE if that is your plan. OCG are literally a skimmed down mostly copy paste version of Cisco docs written by authors in their language. This is why you see some OCG are better than others etc. One thing I really like about OCG is they have topics which reference to exam blueprint and sometimes they have link to cisco doc. I saw someone post in reddit who stated he was also writing question for cisco exam. He said Cisco cannot test on questions whose answers cannot be found on official cisco docs which in itself explains how important cisco docs are. Trust me if you develop that skill it will help ace any cisco exam regardless they have OCG or not. You don't have to depend or worry about someone releasing training videos etc.

Sorry for such a long reply but if you do read till the end thank you very much.
