Original trilogy I would say star wars is probably better (Just by a bit), but if you take into account all 6 movies of each, then lord of the rings wins, the hobbit movies werent great, but they wernt phantom menace bad.
The Hobbit movies sucked a donkeys ass... and the LOTR movies sucked even more donkeys ass, so no.... not even if I include all 6 movies... Star Wars still wins by a mile and more...
