I missed that one, so the other differences I see are that iReal has the capability to use folders for organization, has an internal blacklist function, and can do text to voice. Each of those is probably a must have for some people.
Both these apps are relatively expensive as apps go, but either is a good price for an app you'll use as much or more than any other on your phone, if certain features are dealbreakers in your mind. For me, adding four features I wouldn't use versus one that I use constantly isn't worth the extra $4.
