Just go out, buy yourself Oblivion (Game of the year edition) and kiss your life goodbye! 
Having the PS3 and the 360 I can say I prefer the PS3.
It is a LOT quieter!
The controller is just more intuitive than the 360.
It has wireless internet access built in (no £60 [smiley=shocked.gif] extra required!)
So far no issues with playing PS2 games (I have the 60gb version with the emulator) and they look good with the upscaling.
User menu is straightforward.
Plays BR discs and makes normal dvds look very very good on my tv. 
Ok, the 360 has a much better online commuinty setup and a far wider range of games, but I just think the PS3 is the better choice...
Point 1) You oviously don't have your surround sound speakers loud enough, playing COD4, which the sound up, you cannot hear the x-box! Although i would admit its noisey
Point 2) Have to disagree, i find the 360 controllers much easier to aim with and more naturual, i love the trigger positions. But this is personal choice....
Point 3) This is the whole point of a console for me, i completed COD4 single player in under 2 days. I only play it online now, and its what keeps me interested, so decent online play is critical!
When i got my 360, PS3 was considerably more expensive, at the time, 360 was better for the money. Now its very difficult cause the PS3 is a lot lower....
Of course the 360 would always win for me.... cause of Halo 3
