It has an autotype feature. It generates passwords according to user-defined specs. There are plugins to enable autofill in browsers (this feature is a plugin because of the security implications of granting the browser access to the password database).It automatically wipes the clipboard 15 seconds after you copy a password. It does store memos, and additionally has user defined data storage fields.

I used LastPass before I switched to KeePass. KeePass is feature complete, although it's not quite as a polished as LastPass (which shouldn't come as a surprise, since LastPass is a commercial product). Unlike LastPass, KeePass is open source, so its security can be audited by anyone. The only feature I'm aware of that LastPass has (or had when I used it) which is unavailable in KeePass (and made possible by the centralized nature of LastPass), is the ability to share login credentials to a specific site with other LastPass users.
