Could someone compare XBOX-live vs the PS-Network?

Your talking about renting stuff on the 360. I just wanna point out, I was looking at the 'aquired keys' on my PSP, and for my PS1 game I downloaded. (medievil) it has a 'time avaliable' slot. So you can obviously rent stuff for the PSP. EDIT: When the service is provided.
