Look at something like Red Dead Redemption - it looked better than Alan Wake (360-exclusive 3rd person shooter that came out on the same day) and it looked better than Infamous 2 (PS3 exclusive open world third person game), so Rockstar definitely tried to push both machines but the PS3 just couldn't keep up. By then the Cell architecture had been already researched and demystified by devs.
Not that simple. the 360 was the lead platform for Red Dead- as it should have been as the 360 had much greater marketshare in the US where the majority of that title's sales would be.
Architectural differences between 360 and PS3 (mostly the unified to split ram situation) means that titles developed that way are going to see performance hits on PS3, versus titles that are natively developed around the PS3's strengths and limitations in the first place.
and yes, while infamous 2 is open world, that game didn't have anywhere NEAR the budget of Red Dead.
LA Noire on the other hand used a modified version of the same engine, Led on PS3 vs. 360, and was significantly better than the 360 version in terms of lighting and frame rate.
