Maybe I'm wrong, but I don't think there's any difference between the different tools when it comes to accuracy. All the various tools simply report the fuel useage from the ECM. The accuracy or inaccuracy is determined by the ECM's accuracy--not the tool. Now the various tools may have different options for calibration, which may be able to compensate for ECM inaccuracies, but it's the ECM estimate itself that's acually the root of the problem.
At least that's my understanding. I may be wrong.
