Roles of Portfolio Managers between, different, accounts, couple

Makavelim3

Hello!!!
According to the CFAI and my local CFA Society, majority of the CFA charterholders are portfolio managers.  On my last CFA meeting, I had a chance to talk to couple of PMs.  My understanding is that a PM with a CFA charter is no different than a financial advisor.  Like financial advisors from wirehouses, PMs meet with their clients and manage their accounts.
What are the differences between a financial advisor or an RIA with say, a CFP and/or an MBA to a PM with a CFA charter?
Also when I look at PMs at say, JP Morgan Asset Management, these guys actually manage a mutual fund or funds.  Most of these guys have a CFA charter and an MBA from an impressive business schools.  Are these PMs any different than PMs that manage client portfolios?  What is the route to take to become a PM for JP Morgan and what is the route to become a PM at a private wealth management?
Thank you in advance for your inputs and insights.
