"from the point of view of the user experience is better"
Well I don't think a lot of users have a better experience now there password is exposed.
Agreed it would be nice when your old password could be recovered. But a lot of people will understand that you don't want to store there password and they will accept the fact they have to make sure they remember there password.
When you know a website doesn't store your password you are likely more willing to provide a password you can remember well.
I was not referring to the user experience once the password is leaked, but if everything goes well :) But I understand your point. Part of the user experience is being comfortable with the handling of his private data.
