The hobbit gets serious hate because early code was crap and the vendors set em up at such a weak pitch the balls just floated. BOTH items ruined the experience. Setup correctly it's a serious contender for fun!

The two games are also 5 miles apart in play ability differences.
I think the're both good machines. You'll likely gravitate towards what theme you relate to the best.
For me being a JRR Tolkien nerd it was a no brainer to buy a Hobbit to sit next to my LOTR
