Its all about feel!!!
There are like 4 or 5 Z series Bows to shoot now, so if you have the ability to shoot them all do so. Also, Take into consideration how you will use the bow, for hunting i am going to assume. DO you need more speed, its not a bad thing but it does come at a price. Do you want a more forgiving bow, longer brace heights tend to be more foregiven, do you need a longer draw? At your Draw Length, and Draw Weight are they that much different? But mainly focus on feel, if the bow feels good you will most likely shoot it well. Elite and Mathews both Make excellent bows, either one will get the job done, and get it done well. The best advise is to weigh them side by side and see what works for you..... Also, another bow to try would be the Monster 7, little faster then the Judge, little harder draw though. Got to ask yourself which is going to be the best for you. Compare the speed, vs the draw cycle and balance, compare them all across the board, then make the decision, its a tuff one by the way.
