A number of people have been complaining that unlike Accordance, Logos does not offer a $50 collection. That just is not true. If a person purchases the $50 NAS Electronic Bible Library and then downloads all the free products Logos offers they would have a very competitive starter library.
Bibles: Winner Logos
Both have the KJV and ASV. Strong's numbers are in the KJV, ESV and NASV95.
Accordance has the ESV, but Logos has the Lexham English Bible, NASB95 and Amplified Bible.
Greek Bibles: Winner Logos
Accordance has the Textus Receptus, but Logos has the SBL Greek NT w/ critical apparatus.
Commentaries: Tie
Both have Matthew Henry’s Concise Commentary.
Accordance has the excellent IVP New Bible Commentary, but Logos has the almost as good Faithlife Study Bible and the Commentary Critical and Explanatory on the Whole Bible.
Bible Reference: Winner Logos
Both have Easton’s Bible Dictionary and New Nave’s. Each offer cross references, Accordance based on the ESV and Logos on the NASV95.
Accordance has the Eerdman’s Bible Dictionary, but the Lexham Bible Dictionary is better IMO.
Original Language Lexicons: Tie
Both offer basic Hebrew and Greek dictionaries.
Theology: Winner Logos
With Logos you get the Institutes of the Christian Religion and Crucial Questions Series (17 vols.)
Parallel Passages and Harmonies: Winner Accordance
The Accordance package comes with 7, Logos has none.
