GTA IV looks better on the PS3 due to less texture/graphics pop-ins, worse distance texture detail on the 360 and better lighting on the PS3 version (the guys at Beyond3D all agreed on this, the source of resolution differences, it may well be the 360 version also scales to 720p but doesn't show the usual patterns associated with this). With regard to framerate I only saw a biased Eurogamer comparison comparing the framerate of the cutscenes. The PS3 version ran at roughly 24 FPS for these cutscenes, so on par with Hollywood movies.
Rockstar already clarified this is just their first attempt on the PS3 and their game engine hasn't been well adapted for the PS3 yet. They had a year extra to work on the 360 (and thus designed with its capabilities in mind). They also hinted that for their future games DVD will not be sufficient, they already had to make sacrifices.
