I agree
As far as the programming logic is concerned Unity3d is not the best
The if(GUI.Button ... line is called twice for each frame
the first time to check if the button has been created the second time for the click event
It is not logic
More over the documentation is really poor for a 1500 usd engine
See for example my post about vertex manipulation
I was wrong, ok, but if you go through Unity docs and tuts , well it is not that evident
Well if you come from Torque ,the lack of doc should not be a problem for you

However the Unity3d strong points are speed and reliability not to mention the fantastic editor
I tested many other new engines : Leadwerks, game core, dxstudio, visual3d ...

None of them can compete with Unity
