I get the feeling that Magavara's comments were a bump and run.
In agreement with Michael Hanel and Sansom48: It reminds of the owner of a business (maybe a print shop) who put on their card, "Speed. Quality. Price. Pick any two." :)
I've worked and worked at this, and finally (feel like I) came up with a concise way of comparing and contrasting Logos and BW.
I've tried to explain the difference to my students like this:
BibleWorks starts with the biblical text and extends outwards to all sorts of related resources (text critical matters, translations, lexicons, grammars...)
Logos is a library management system that looks deeply into texts, including the Bible, and provides the connections between all the books in your library.
(And Accordance is kind of in between but with an inclination to start w/ biblical text.)
