I own a 360 and a PS3 and really 90% of the great games out there are for both so it's hard to compare the 2 on anything other than controller design and 'slightly' better graphics (in my experience usually the 360 has the advantage but there's a couple where it looks better on the PS3... but not many) I'm only talking about the newer generation consoles though I never owned a PS2 or original xbox. Personally, between those 2 I prefer my 360 though there are a couple games on the PS3 that make it worth owning but those games are few and far between and I just prefer the feel of a 360 controller
I actually like nintendo's handhelds better than sony's because,the newest PSP they fucked up on that they made it so you cant play orignal PSP discs on it.I have a DSi and prefer there games much more than the PSP games.But when it comes to consoles I like xbox/playstation games much more then the wii games.
From a purely technological standpoint Sony totally dominates the current market. xBox is good, but the tech just doesn't really compare to Sony. The other thing that got me away from xBox (aside from the fact that every one I've owned has crashed) is that all of the 'XBox Only' titles are also available for PC, so when I got rid of my last 360 I just started buying the games for computer. I use a PC game controller and it's just as good as playing on XBox.
Nintendo was great, and they still have some good titles, but for the most part none of the games interest me enough to justify another system.
I am a Nintendo freak. Nintendo's consoles are reliable, would not break easily and would not spoil for a long time. For example: my Super Nintendo is still working.
Nintendo rocks. Especially the DS and Nintendo. They even have some of the most popular video games ever! Super Mario Bros., Mario Karts, Kirby, Pokemon, and I think they even have Sonic the Hedgehog(Sega and Nintendo joined forces, right?) Nintendo has my most favorite games ever. So therefore, of course I would have to say Nintendo.
