Borderlands system?

So I wondered if there was a clear difference between Borderlands for PS3 and Xbox 360? Like 360 got an 8.5 while PS3 only got an 8. What's the difference between the two? And will DLC be different on each? I guess my question is: Should I get it on 360, PS3, or both? Thanks

The reason why PS3 got a lower score is because it launched with a broken friends list functionality. Obviously, that's a major downer if you're trying to play with your friends. However, a recent patch came out which fixed the issue, so it really comes down to which console you prefer playing on the most. The game is best when playing with other people.

So does that mean that there isn't a big difference between the two? Like the DLC is going to be the same?

There is really no big diffrence now. The DLC will be the same, the first being Dr.Ned's Zombie Island.

So it's not worth it to buy it on both systems? Because I had heard that there were some differences.

No, that would definitely be a waste of money. There are no exclusive DLC packs for any console as far as I know, so you wouldn't be losing out by just buying it for just one system.
