In terms of technical specs, the PS3 is far better. The processor is alot more powerful, it has a built in Blue-ray player, and as the games are on Blue-ray format and not DVD like XBox, there is 4 or 5 times the size of memory, for more detailed games. However, because the hardware is alot more complex on the PS3, games developers, find it easier to write the games on the XBox's simple format, and then port it over to PS3. Therefore, 90% of games look, and play the same on both formats. The real potential of the PS3's power, is only show in a few PS3 exclusive tittles like the Uncharted series. And although the XBox doesn't have a Blue-ray player built in, you can buy the units separately as add ons. I only own the PS3, and i chose it because I had the first 2 Playstations. However, as an end consumer, now the prices are pretty much identical, there really isn't alot of difference. If you don't have a Blue-ray player, i would 100% say buy the PS3, as you can save alot of money buying one separately. If the Blue-ray player is not an issue, then i would just look at which of the exclusive tittles you would prefer to play, and how the controllers feel. Although looking at the date of the original post, i'm guessing you've already bought and gotten bored with whichever one you chose lol.
