Both manga are based around the 1 girl, 2 guys love triangle deal. The female leads are both cute and cheerful girls with a lot on their plate. They both have supernatural themes without being overly annoying about it (imo). If you liked one, I would say that you would almost definately enjoy the other.
The layout of these series is very similar. You have the lone teenage girl who, for various reasons, can't live with her family and ends up living with some guys instead. Complicated relationships, dark secrets, teenage love and much hilarity follows.
If you liked either Yume Miru Taiyou of Fruits Basket you're sure to like the other!
