I believe that Accordance is certainly the best Bible software in the world. I own both Accordance and Logos, and Accordance is certainly superior. However, in this one area Logos has you beat. In Logos, the read aloud feature allows one to read entire books, with the book scrolling down the screen as it is read. This ability to read entire books is very useful to me because I often have my computer reading books to me while I am commuting or otherwise engaged in humdrum tasks – I have had many books read, and learned a very great deal, because of this feature of Logos. By contrast, Accordance will only read aloud a maximum of 100 verses. This is vastly inferior to what Logos will do and makes it impossible for me to employ my Accordance modules in the way that I employ Logos.
By the way, if you want to make Accordance superior to Logos, then make the dictate feature one that can read Greek and Hebrew in a realistic way.
