I don't think there is a good comparison between the two because they're
different technologies addressing different problems.  JMS is a messaging
middleware defined at the Java language API level (hence the need to for
STOMP protocol and similar adapting layers for use with Python or other
non-Java languages).  PB is a "secure, easy-to-use Remote Procedure Call
(RPC) mechanism."

For the system you're descibing it seems like message middleware is more
what you want.  Unless you want to implement your own load balacing, work
distribution and failover algorithms?  Another alternative to ActiveMQ is
RabbitMQ which implements AMQP, which a Python client can speak directly
without using a limited protocol like STOMP.  There's also handful of good
AMQP python libs including one for use in Twisted: txamqp.
