Actually, I never found a real difference but I always take advantage  
of a location or another:
For instance, openCard in the stack's script will be triggered by any  
card.
At the contrary, preOpenStack in the first card's script will only be  
triggered by the main stack but not by its sub stacks, etc.
To get a reliable code without any repetition (indispensable for a  
reliable maintenance), it is often handy to put handlers at a high  
level using parameters in addition to get the most generic code you can.
If you have 2.8 you might be interested in the new 'private' command  
(but only for your custom handlers) that allow to gain speed.
