"Fun Home, like most musicals (except the really good ones by Sondheim, LaChiusa, etc.) tells you what you should feel loudly and in song. If you want to have any kind of interactive experience, one that makes you think and feel, go with The Humans."
You're thinking of The Phantom of the Opera.
Fun Home is a beautifully acted and directed piece of musical theatre.
The Humans is a beautifully acted and directed piece of straight theatre.
It's really a win-win situation, but personally I'd go for Fun Home, if only because it will go down in the record books. I also feel like I got more bang for my buck, and an actual STORY out of Fun Home, which you can't really say about The Humans.
