Commentary mirrors study bible text notes. Has some appendix, sidebar differences, same otherwise. Check the toc for both, if you already have the study bible, to see if the appendix/sidebar differences are worth it to you.
Great job by Logos (as usual). Fully searchable. Inline search is especially helpful in works like this. Lack of page numbers may be a drawback for some but would be an unnecessary distraction for others. Regardless, great overall functionality, leveraging of Logos capabilities.
