Personally I prefer Xbox 360 over PS3,but since I am living in Malaysia not US.I think PS3 is a better choice for Malaysian since it is more region friendly and easy to get games and buy DLC.

As for 360,it shouldn't be a problem to get the games as some dealer like pbbseller bringing in X360 games too,but the problem arise when comes to DLC(example COD map pack),many people I heard suffer from buying Black Ops DLC and others DLC too as it is region lock.

So basically X360 is more approach to US user and north/south America country while PS3 is more towards Europe and Asian country.

PS3 and X360 is not a much difference though in term of graphics,online,...............just depends on where are you living

I am using PS3 by the way
