This is a tough one as both are incredible pins. I love LOTR and have owned two of them over the past 10 years. The Hobbit is a special pin as for one its a loaded widebody, has multiple interactive mechs, features custom music from a Hollywood studio, has some of David Thiels best audio work, and comes with what may be the deepest objective based rulesets ever created for a pin. The theme integration is off the charts too thanks to it having full assets and the incredible amount of work done with the final code updates. The Hobbit is the ultimate adventure pin.
I've mentioned this is another thread but I have a cousin that has owned a LOTR since new, he's put over 6k plays on it. When he comes to my house he only plays Hobbit as he loves the game that damn much lol.
Also, waiting for Cscmtp to enter the thread and complain about Hobbit for the 500th time
