I got the PS3 version of BioShock.
I did the 1.1 patch, and with the blur filter gone, the game looks just as sharp as the 360 version, and the badly pixelated Big Daddy look 'normal' now.
Which is all good of course, however it was clear that some compromises were made.
I discovered that some of the objects have been removed, which I had noticed when I was doing the comparison with the 360 version, and I had to download the PS3 demo to confirm this.

the Bid Daddy look good now
And one more thing, the retail version of BioShock provides the frame rate unlock option similar to the one found in the 360 version, however the things work differently.
On the 360 you get smoother frame rate with the horrible screen tearing, where the PS3, the V-Sync option remains, but it just removes frame rate cap, which I believe is around 25.
With the option turned on, the game runs generally smoother than the 360 version with the frame rate lock on (30fps), but the drop in frame rate becomes more noticeable.
I got my copy just for the DLC, but I'm glad that the changes were made to make the game as good as the 360 version if not better (smoother frame rate with V-lock)
