One advantage of the Lutheran Service Book is that it has in it the Small Catechism.
It's good that one of the two new service books introduced last year is a real Lutheran hymnal.
I've posted a few times on ALPB forum that if I were forced to use a new book I would take LSB over ELW without hesitation. Of course, the older I get the more I appreciate the 1958 Service Book and Hymnal, even though I never worshipped where it was in use. There are some excellent collects, including for the conversion of those in Islam and for the Armed Services. We'll probably never see anything like that again in the ELCA.
