PS3 Cell of course. Much much better (8 independent processors vs 3 cores at same clockspeed, the SPEs can do a much better job than the PPE or a 360 can at well designed tasks for them to accomplish) and not only that, the way it's implemented in the PS3 architecture counts also. The Xenon has to share its L2 cache amongst all three cores and access to main memory provides far less bandwidth as it has to share the bus with the GPU and the PS3's XDR Ram provides much lower latencies.
