I made a post a while back comparing The Lord of the Rings with Game of Thrones, and I argued that Game of Thrones was better. It made for a pretty interesting convo with a bunch of us nerds quibbling over fantasy lands and stories.
Granted, I will say that after watching The Lord of the Rings trilogy about a dozen times since then, my opinion has changed somewhat, and I think they're much closer than I had originally thought, though I still give Game of Thrones the edge. The more I watch The Lord of the Rings the less childish it gets and the more I relate to the characters.
I was not a fan of the Hobbit trilogy at all, though.
