pygame offers a bit more functions but most users won't use them 99% of the time and I believe you might be able to do most of them in Pythonista if you dig in the c functions.
pythonista is a higher level library so you can make stuff faster, with fewer bugs, and its easier to learn.
I am currently making the scene module in pygame so scene will hopefully work on pc and ios where pygame won't work on ios.
