The riser is definitely longer on the Allegiance. Hence the $50 higher price tag in the 2 shops I saw them in.

The advice that I gotis that if you have a long draw length you are better off going with thelonger ATA Allegiance. If not it's your choice. I'm pretty sure they both have the exact same cams. Therefore, I do not see how there could be any discernible difference between the 2. Except if you take into account what Lebeau is stating.
