Java == python gae functionality - > Not yet things like geopt properties don't exist yet for java, but they no doubt will. The bulkupload service in python doesn't exist in java yet, but no doubt it will
The big difference between the two I think you will find is the python implementation of a service is more than likely going to be simpler (code wise) to read than java. Java will no doubt have some very advanced libraries that you might shoe horn into gae that don't exist in python. Java might run faster but we will have to wait for some benchmarks. My bet is python gae apps will possibly startup quicker if the app is purged. You can get php on top of java, you won't get php written in python ;-) At the end of the day use whichever tool you are comfortable - (knowing that java is way more experimental on gae at the moment) I personally will stick with python. Java just adds complexity that I find unnecessary ;-) but I am not trying to port existing apps to gae. Just my 2c worth.
