John Carmack, id Software's coding genius has in a recent interview shown on G4tv made some statements regarding the PS3 Vs Xbox 360 issue. Though this is only the opinion of a high profile programmer, his opinion should be a lot more valid than the millions of forum posts on the subject.
Basically he says that the PS3 is more powerful, but the 360 has better development tools and is his preferred console to develop for.
"I make little nitpicky decisions about say, well, I prefer the symmetric approach that MS has over the asymmetric Cell approach, but you can do great games on either one of them, and I make fundamental decisions based on development tools and depth of documentation, which Microsoft has been superior on," he added.
When speaking about the power of the hardware Carmack said that "the hardware is comparable" but went on to say that "PS3 is probably marginally more powerful, in terms of raw flops and graphic operations.”
But according to Carmack having the better development tools is more important. "When you look at these development cycles that stretch over years and years, being 20% easier to develop on is much more important than being 20% more powerful", Carmack said.
However, if we had asked Kojima if the PS3 development tools are inferior to those available for the 360, we would probably get a different answer.
