Are there any? Not trying to start a flame war, just technically are there any I should know of before I make my choice.

I would horribly surprised if there were any technical differences.

Well for a few more hours the PS3 version is a few bucks cheaper thanks to a PSN sale.  Other than that maybe pick based on controller preference? 

The controllers are different... Which do you prefer!?

This won't start a flame war, this isn't like those other forums, you have to make a thread so horribly stupid that it hurts to do that here (most of the time)
 
On-topic, I have no idea.

The PS3 version used to have freezing issues, but they were fixed in a patch, so it's pretty much whichever system you prefer. For me, the PS3's non-shitty D-Pad made it an easy choice.
