IMHO
Erwin is much easier to use. However, it doesn't support the logical level
as well as Designer and it doesn't support the application level at all. But
on the physical level there it's robust and much easier to use than
Designer.
They're really different animals. Designer is an Information Engineering
workbench (or it likes to think that it is) while Erwin is ment for
supporting the physical implementation of an already designed database.
Of course, I haven't used Erwin in the last 3 years so later editions may
change the feature set.
Your milage may vary.
