lol, now it's fairly obvious you are just trying to start a console war. The link I gave provides a clear side by side comparison with a CONSIDERABLE difference. If you read the article you'd notice the PS3 version suffered frame rate problems, muddy textures, etc. Bayonetta WAS a big name released that is touted as an action title as competent as God of War.
360 has a superior GPU and the PS3 has to devote a fair amount of the processor towards making up for the shortcomings of it's GPU. Here is a http://www.youtube.com/watch?v=989MBOiIghA of John Carmack, a highly respected developer/programmer, discussing the differences of the platforms. Note: the volume is extremely low so headphones are suggested
I find it laughable that you insinuate that Microsoft would pay for reviews. Sony is much more liable to throw money around in the gaming industry as evident by the sheer volume of developing studios that they have bought out over the years in an attempt of monopolizing IP's.
