What are some reasons you would consider an Investment advisor or Relationship manager to handle your investments?

They have a guaranteed higher returns.

Am working in a FI and a role where I'm exposed to institutional trades daily. If I were to maintain my own portfolio and trade, I would have to go through compliance approval for every transaction I want to execute. In order to rid of all the troublesome back and forth as well as ambiguity of insider trading, I engage an FA to handle DCA investing on behalf of myself.

Never, simply because he/she will never care about my money as much as I do.

They have more connections, see and hear more info not easily available to retail investors.
