The problem with password managers from Norton, Kaspersky, F-Secure, etc - is that their password managers are not closely tested nor actively developed.
At least with LastPass there are many dedicated users that - when they find something wrong - will report bugs\vulnerabilities and Marvasol (LastPass publisher) fixes them.
Report a password manager bug to Norton, Kaspersky, F-Secure, etc - and it is likely never to be fixed or - if it is fixed - the fix will come years later. For example, Kaspersky's password manager did not function on 64 bit systems for years. I don't know that it does today.
LastPass new releases are few and far in-between; security soft password manager new releases are almost never.
In terms of protection, I trust LastPass over others.
