Why are you guys focusing on download speed? Even if they were equal, which they are for some people, the act of downloading patches, installing games, and syncing and comparing trophies is a worse experience on PS3. Also I feel like PSN has a great library of downloadable games. It's certainly not ghetto either.
OK, speeds aside. As an avid user of both consoles yes the 360's service is appreciably better by a long shot to me for reasons (not counting speed):
- No synching of achievements. It's automatic
- demo for every single XBLA game. Every one.
- can update my username if I feel like it
- update process on games literally takes seconds rather than hours
- transferring purchases/licenses is a breeze on 360. Ability to filter all my purchases on xbox.com and pick and choose what I want redownloaded is far superior to the list of everything you ever bought that Sony presents you with when you want to go back and re-download something.
- from a personal standpoint, HBO Go and ESPN 3 are my favorite video apps. Netflix used to be superior on 360, but the latest update made it as shitty as my PS3's Netflix app, so now I use the superior Netflix app on my Apple TV.
