Choosing Java vs Python on Google App Engine

Question

Currently Google App Engine supports both Python & Java. Java support is less mature. However, Java seems to have a longer list of libraries and especially support for Java bytecode regardless of the languages used to write that code. Which language will give better performance and more power? Please advise. Thank you!

Edit: By "power" I mean better expandability and inclusion of available libraries outside the framework. Python allows only pure Python libraries, though.
