Longer axle bow are more forgiving, steadier, better balance and less string pinch. The first shorter compounds where hard to shoot. How days the shorter bow has longer risers, shorter limb, parallel limbs and with higher brace height that help to make the shorter bow a lot more forgiving then the first ones. The loop has helped us to be able to shoot them with the string pinch. Longer bow still have some advantages, but the shorter axle bows are getting there and are a lot easier to shoot and are great for a hunting bow and are starting to move into the target picture.
