FYI, we Mormons are Christians, too.
Being Mormon, I'm not qualified to answer your questions. I hear mixed reviews from non-Mormons. Some like it fine. They appreciate the fact that the crime rates are low and the environment more family-friendly than in some other places. Others really resent the fact that the dominant culture is different from their own.
I suspect it might be like a non-Catholic living in Rome.
If you decide to come: Welcome.
One of the facts that makes me proudest of Utah: We are the only state in the nation in which Clinton came in third, after Perot, in 1992. Go, Utah.
