Both consoles are the same graphically. The only way you'll see any difference between the same game on both consoles is if the developer has took the time to either port the game better for one console or hasnt done a good job of porting it to the other. a 360 can display exactly what a PS3 displays. and vice versa. none have any graphical advantage over the other. a different story compared to the last-generation consoles.
360: if you simply want to play lots of games and are therefore willing to pay yearly for your online gaming. It is also more focused upon gaming on its own because it was never built to be a media center. But microsoft are trying to keep up with the PS3 by offering HD-movie downloads via xboxlive. Although it is at an immediate disadvantage as it uses a standard DVD-drive so has no direct high definition movie capability. The 360 has the largest game-catalogue because it's older but PS3 isnt far behind. 95% of all new games on 360 come out on PS3. Infact PS3 has more exclusives either in development or recently released at this moment in time.
PS3: Like movies? have a HDTV? PS3 is an absolute star for you. The PS3 is probably the best media center on the market. Even if you leave out the gaming capability. Blu-ray quality movies on a HDTV is quite something to behold and it is better than almost all standalone blu-ray players on the market. yet its one of the cheapest because it has to be in order to compete against the 360 in sales. Bargain in every sense of the word. Also, as mentioned previously, the PS3 has alot of exclusive games released in 2008/09 and more to come. You rarely find a game that isnt released for PS3 at the moment. Which is very good news for any big gaming fan because you can always look forward to the big titles.
For me, with my preferences and my needs for a console as a media center for blu-ray and next-gen games the PS3 is my first choice. But others needs are right where the 360 is at. You decide
