I think both religions are whacked. I know a LOT of both and the LDS win for being good neighbors in the literal way and the Jesus way. JWs can't touch them.
If all religion removed all the "spiritual" and doctrinal stuff and was left with the Christian 'life', the JWs would all be just plain dead. Mormons practice their religion in practical and truly neighborly ways. They help each other and their neighbors, their tithes support the things that the church does (and they do a LOT-their tithes support the community in the way they should). I can name some stinkier things that are official doctrine, but in everyday life, they practice being good neighbors and I think Jesus (who I believe existed) was more interested in informing what we do than what we blather about.
