I am a newbie to PyQt, but have created and published a simple app. I would like to make a few improvements to it.

I have been wondering what the pros and cons are for choosing between importing uic to load the GUI.ui or using pyuic4 to convert the GUI.ui into a .py file.
The first method is simpler for testing, but the second creates a .pyc file after the first run, so I imagine that it loads the GUi and app quicker. It's difficult to do a comparison as other factors are involved. Speeding up the loading would be helpful. have tried to assess the advantages of method myself but have no experience to base this on. A web search hasn't helped as it doesn't seem to be discussed.

What are the advantages and disadvantages to each method - I'd welcome opinions as well as facts.
