PS3 proabably is the most advanced, considering the money poured into the Cell. I mean, if Sony wanted something on par with 360, they'd just pay for some already-made Intel chips like Microsoft does.
The problem is that the console generation is only so many years long, and Sony has to make it quicker and more affordable for devs to produce PS3 games. That's where the problem will lie for many years still, I believe.
