There are some sites that try to disable the ability to save passwords and 3rd party password managers usually override this. Another thing that's really nice is having the LastPass extension on Firefox, Chrome, and Safari on the same computer and not having to worry about if they are using the system keychain or not. In my experience, form filling with credit card information has been less error prone with LastPass as well. I thought at one point Safari was requiring the CVV number to be manually entered too. I could be mistaken.
