If you're wondering what the 360's main advantage over ps3 is as a GAME console, it really comes down to 2 things:
1) Better multiplatform games
2) Exclusives
Nearly any site, from Kotaku to DigitalFoundry will tell you that 9 times out of 10, a multiplatform game is gimped on ps3 compared to the 360. It's really common now that games that come out for both systems be it Resident Evil 5, or Street Fighter, or even Assassin's Creed run better on 360. I don't say this to start any flame wars but it's the simple truth (almost all the tech comparison blogs where they actually use framebuffer captures find that the 360 version usually has more anti-aliasing and run at slightly higher resolution and framerates than the ps3 counterparts).
This has nothing to do with the "strength" of the system or "laziness" of developers. It really comes down to the fact that when you're programming a game that's gonna run on 2 systems with architectures that need very unique optimizations, you're gonna go the most cost effective route. The majority of games don't have the luxury of having huge budgets that can sustain a 3-4 year development cycle. Unfortunately, the ps3 coding takes more time to make efficient so often times it just gets gimped. There are a couple exceptions to this but it's plain and simple that most multi-platform games run better or with higher settings on 360. Examples include the games listed above, the tom clancy games, soul calibur 4, GTA IV, EA Sports games, etc. Most of the exceptions (i.e. multiplat games that run better on ps3) come from games that were released on the 360 but a year or 2 later came out on ps3. In that case, they could optimize and even improve with added time and experience.
All of the above, btw, is supported by tech and developer analyses which you can read up on at real tech forums such as b3d or digitalfoundry and not random gaming journalism pages (i.e. neogaf, gametrailers, etc)
So anyway, I use my 360 for almost all multiplatform games because they simply run better. Xbox live is a plus because it's consistently reliable. The exclusives are great too. I use my ps3 for blurays and exclusives. I'm a huge fan of some sony only games like god of war and metal gear and I'm not here to argue whether exclusives on one console can be done on the other so I won't.
The main thing I'm getting at is that multiplatform games, though theoretically identical, really are not and more often than not, you're better off getting the x360 version if you want the 'flagship' version.[/quote]
Plus, they have achievements!
I'm not trying to doubt the veracity of what you're saying here, but I have to believe that the differences you're describing are probably insignificant enough to (most) players that they're not a primary factor. For example, I consider whether I think the game is suited to the PS3 or 360 controllers better before I consider slight graphical differences. For example, availability of DLC is what led me to get Fallout 3 for 360 rather than PS3, nothing else.
I'm not trying to support one side or the other, since I can't even decide for myself which of my babies I like more (and like most proud parents, will continue to insist I love both equally, even if that's not true).
But as for the superiority of the 360 as a gaming platform, while your argument has merit I'd say that you can't ignore the blu ray factor. For example, maybe Final Fantasy XIII will follow your argument and look better on the 360, but I can't imagine it doing so in any less than three discs.
