GUIKit02 vs EZ GUI vs Others?

I like the nice gamescene scroll of the GUIKit02 - are there EZ GUI add-on’s that do something similar? Is there a comparison of the various GUI toolkits?

Having made GUIKit001 I can tell you that the main difference is that GUIKit001 contains a complete ready-to-go game menu that uses UnityGUI (Unity’s included GUI System), while EZ GUI is a new GUI System. So ready-to-use menu -vs- sprite-based GUI system
