Gah !
It all depends on how it's implemented, I think I'd prefer comunism, seeing as then at least part of the money I'd have to give will go to the people and not into funding essentially pointless things, like more church buildings, a university where all you do all day is reading the Bible or funding a 'class' of people who only 'serve' God and don't do any other job.
Poverty for anyone not in the religious class or party would be your fate in either society. I don't see why you're focusing on redistribution of wealth, since their won't be much wealth to distribute.
Note: I know there are rich people in China, but then they're no longer really communist, more totalitarian-capitalist, if that makes sense.
