How does
1. Understanding BHS by Wonneberger, Reinhard Editrice Pontificio Istituto Biblico | 1990
http://www.logos.com/product/2927/understanding-bhs
compare to
2. The Masorah of Biblia Hebraica Stuttgartensia by Mynatt, Daniel, Crawford, Timothy, Kelley, Page H. William B. Eerdmans Publishing Company | 1998
http://www.logos.com/product/3805/the-masorah-of-biblia-hebraica-stuttgartensia
I have the first but not the second.
What would I gain by getting 2.?
Thanks!
