Buyside - Listed Company vs Partnership/Privately Owned

Does anyone have any insight about the relative benefits of working for a Privately owned firm (eg Wellington) compared to working for a listed company(eg Blackrock)? Is there really any difference to your day-to-day job or career progression?

So far in my career I’ve only worked for buy side firms that are Plc’s. Not by design, just the opportunities that came up. The last place I worked was pretty bad for Senior Management being totally obsessed with pumping up the share price above all else. I appreciate the irony in having an issue with that.
