Joseph,
Christians and Conservative/Reform go to their Church or Temple once a week, if even that. Jews go three times a day. So to compare, is to miss the mark.
That may be, but I think it has more to do with the structure and purpose of the respective services. Christian and Reform services are akin to performances – there is instrumental music, theatrical sermons, etc. and the congregants are largely a passive audience. The central aspect of Orthodox Jewish services, on the other hand, is tefilla, which is personal, and congregants must be active to fulfill their obligations.
