The "best" one is the one that makes sense to you -- the one you can 
maintain in the future.  The overhead of running Python (as opposed to 
C++) is going to swamp any difference in performance between various 
techniques of handling the message loop.  That's true of user interfaces 
in general; the typical user interface application spends 99.9% of its 
time waiting for the next message.

I'm a Python advocate, but if you need to squeeze every microsecond out 
of your drawing code, then you probably shouldn't be writing it in Python.
