Is the PSPO certification worth it?
I am doing my master degree in software engineering and had a agile course last year. I just passed the PSM I certification yesterday. Right now, I have a lot of classes about project management, human resources and project estimations to eventually become a team lead. My current team lead has a PMP certification and acts as the product owner for our software.
I was wondering about the PSPO certification and if it had any value in my case or if the PSM I certification is enough.
I would suspect strongly the course would be valuable for you, though consider my bias and my caveat. I'm soon to be a Professional Scrum Trainer and have not taken the course personally; however, I've interviewed several people who have taken it and all so far report a great experience that helps them professionally.
I strongly suspect you will find value there given both what you describe as your near term professional course and the current software development environment.
I would encourage you to take the Open (free) PSPO assessment to see the sort of things you will be taught:

Also, find a course that seems viable based on your needs:

Then, reach out to the trainer who will teach the course, and reach out to them:

Ask them your hard questions. Ultimately, I believe this approach will help you more effectively answer your original question. You'll have more confidence in the value you personally are likely to get.
