Just an FYI if your still in basic flight with some inverted but not quiet 3D then any FBL will work. Its when you start tinkering really deep into it. Then your going to want one that suits your needs. You'll be looking at ease of use, flexibility in tuning and programing, default settings, governor, bail out, rescue and the list goes on. All I can say about which one to get is get the one that your flying group flies. That way you get your own tech support.
