I say WOZ; I like LOTR a lot but it didn't last for me, just felt kinda clunky and I didn't have that much fun after a while. WOZ is incredibly more deep and way harder, and far more to do. If you don't like the theme though, it can be a deal breaker. The music was kind of tough for me to get past on WOZ.
IMO Hobbit is your best bet if you're looking for that fantasy theme. New code has changed it into a completely new game, incredible. Barring that, WOZ WOZ WOZ.
