PMP or PgMP

I have 3 years of Senior BA, 5+ Years of manager and Senior manager experience in a product company. I have total 15 years of experience including education. My primary skills are Product management, IT product lifecycle management, and Business analysis. I manage multiple projects for last 3-4 years.

Should I go for PgMP or PMP certification? What are pros and cons. Which certification I should pursue in my current careers stage?

Thanks in advance.
