The download speeds on Xbox Live seem to be a lot faster than on PSN still. Maybe it's just me, but that really bugs the shit out of me. I downloaded the same demo (Force unleashed) on both at relatively the same time, and it took an extra 30 mins to get it onto my PS3. What is that about?
Besides that, I honestly think that everything else is pretty close to equal. I still prefer the navigation on Live though.
