The standard UDM creator offers you the following options :
Create Menu page-If you check on this option, it would result in creation of a menu page on the left side of your site created.
Create Home page-If you check on this option you can create a home page which contains the Menu, the Banner on the top and the Dashboard occupying the remaining space.
Access to User Login to all pages-This option empowers you to restrict access to certain specific pages of the site or to allow access to all pages.
Create Login page-If you check this option, you can design the look and feel of your login page. You need to provide the names for the following:
            -  Name for the user login name column
            -  Name of the password column
You could also specify preferences in terms of:
Default paging -You may want to specify the number of records to be retrieved on a single page on the site.
Metatemplate Family-Select the format in which data is to be retrieved based on the family you opt for.
Session expiry time -You can kill the session after a time limit specified by you. This is helpful in preventing the session to continue if the zDE is not being used. Meanwhile, another user can access it. 
The standard UDM creator is more user friendly because:
The standard UDM creator remembers your preferences each time the page is submitted, instead of only when a site is generated.
It gives you the opportunity to examine the most recent site preferences, in relation to the UDMs and pages in the site.
