I believe that the PS3 versions of FIFA 12, 13 and 14 for PC and PS3 are almost equal.
The only thing I can say is that FIFA 14 for PC does suffer from some graphic glitches with AMD cards (nets having a strange "aura" in bad weather/under the floodlights, and crowd disappearing from the stadium under some circumstances) while I'm pretty sure that the PS3 version doesn't suffer from those.
If you play it with RPCS3, though, brace yourself for having glitches with the player names on kits (which do get shown as a solid block of colour from distance).
All the games from FIFA 08 to FIFA 11 are different though: they're more advanced on PS3 than they are on PC.
FIFA 08 was the PS2 version on PC, so it doesn't compare to the PS3 version.
FIFA 09 and FIFA 10 are strange "hybrids" if you know what I mean. Not the same as the PS2 counterparts but definitely not on par with the PS3 versions.
FIFA 11 for PC, lastly, is finally a "PS3 version" but it's a sort of "PS3 FIFA 10.1" with updated rosters and assets.
