I’ve had both PS3 and xbox360 and whilst it wasn’t a smooth ride for me with the PS3, due to quite a few of my 40GB fat model developing faults, the PS3 is a better all around machine then the xbox360.
Few years ago, PS3 was a lacking console. Sony dropped the ball a tad, released it without dual shock rumble pads, no achievement system to match the 360, the PSN was a bit iffy, cross platform games were considered to be a bit or in some cases a lot better on the 360, developers found and do still find it hard to harness its power, however over the years Sony has developed and addressed a lot of issues..
I’ve always said if you’ve got a decent PC, then PS3 is maybe the better all round console, the PSN (despite the recent hacking) is a stable and usable platform now. Cross platform games are on par, and in some cases now better on the PS3, Portal 2 or LA Noire for example. PS3 exclusives are for most part excellent, and developers really do harness the power of PS3 now. Killzone 3 and Uncharted 2 are great examples.
PSN also has some gem little games, PSN+ is also quite handy for £40 a year you got quite a bit of free – well usable whilst you subscribe content. The blu ray player is excellent, PS3 is quite easy to hook up to a PC as a media streamer and I find the user interface on PS3 to be a little better (well I think a lot) then the 360 dashboard.
I sold my 360 quite a while ago, the PS3 and a decent PC is all I need.
I also find the PS move – when it does get used, such as Killzone 3 or Heavy Rain to be better then Kinect, but that’s just me..
The 360 did have the edge years ago, and its still got a very good and extensive back catalogue, but most can be had on PC, so for me, money would be better spent on a PS3, provided you can use the pad.. Sony need to sort the triggers out, tip..!! Get some real triggers to clip on, they do make a huge difference IMO if you do go down the PS3 road..
Good luck in your choice.!!
