Personally using a browser based password manager is too restrictive in that you need a browser to access passwords. I use passwords in a lot of places outside of browsers and often the interface I'm using has no browser capabilities. Understand using browser based password management if you only ever use passwords on the web. But I'm sure a lot of others, like me, need them outside of that context.
Occasionally I need the password for Microsoft or intelliJ accounts, but even then I just use my phone to lookup the password in my manager visually and then type it, I'm never letting any password I care about go into my Macs clipboard!
