A thread like this will invite some person to give a boiler plate response like "Your property management should make you more money" (which they're probably parroting from some podcast they just listened to).
There are a minority of stellar property managers, but the vast majority are either 'meh' or major sources of incompetence and liability.
'Efficiency' - depends on what areas. I dont have the time/patience/willingness to face a difficult tenant or deal with maintenance logistics - those things I gladly hand over to management. However, there is a lot of 'Hey, did you do this____' ...' 'Hows it going with ____' That is inefficient, but one thing to keep on mind is that the squeaky wheel ge td s the attention. When there are 400+ units a management team is stewarding, then you need to work at getting on their radar. This isn't at all ideal or efficient, but c'est la vie. In the market I invest in (Chicago), it would be foolish and a gamble to trade a decent property manager (who is very $ reasonable) for some on ne you take a chance with by transferring management in order to achieve greater efficiency.
