Getting a blueRay player?

I'm looking at getting a high end blueRay player by samsung or pioneer. I am also looking at the sony ps3. The BlueRay players I am looking at is going to be about $900 vs. the ps3 which I can get as low as $399. Is there any major difference or should I go with the ps3 because it seems like more for your money? Sound is not an issue so lm just worried about the picture are there any features that will make a major impact? Does the blueray on the ps3 work differently than any other player? Is it software (ps3) vs hardware (blueRay)?Please give details.
