I thought the E&E for property was absolutely terrible! Gilberts was so much more helpful (especially if you have to learn future interests and RAP cold) and it's golden if you're using the Dukeminier casebook because it was written by one of the authors.
If you're using the Eskridge/Frickey/Garrett casebook for legislation, you may want to check out the authors' supplement. I didn't use it, but the person with the top grade in my class from the year before recommended it highly. I looked at it at the bookstore, and it seemed clear and well organized.
