Are the Christmas week crowds at Universal as bad as Disneyworld?

If you are staying on property and have use of the Express Pass....is it worth going around the Christmas holiday? I've heard it's an absolute madhouse at WDW during this time, but wondered what the thoughts were for Universal Studios and Island of Adventure? Just curious...:mickey:

Never been at Christmas but I would guess it will be very crowded.
