I've had LOTR, Road Show & RFM.

RFM was fun as heck with my kids for a few months. It's not deep, but it was fun to discover all the modes.

LOTR code is very deep and it's a long playing pin. If you love the movies, chances are you'll love it too. It a journey. A quest. Code is pretty straight forward despite being so deep. Try to stage a multiball, then start a mode that compliments it, then stack your multiball. Try to finish a mode and/or multiball to advance and get a gift from the elves. Get To There and Back Again. Fantastic mode. Had LOTR for 4 years. Never got to Valinor.

Road Show is near and dear to my heart. It was my 2nd pin. I loved pretty much everything about it. Took me years to finally beat the high score that it came with, which was over 6,000,000,000. It's incredibly quirky and fun. If someone had a HUO one, I'd probably snatch it up over LOTR, honestly.
