I was given a link this morning to an article that was written in December last year by a games developer who has worked on both platforms.
Given that games will win this console war I think the developers perspective is very important. He does remain anonymous so we cannot say for sure that he is a developer but the article is a very interesting read.
The summary is below and you can follow the link to read more about it.
Short answer: XBOX 360.
Long answer: Price, performance, visual quality, game selection and online support. I think the XBOX 360 wins in every category.
