Here is a run down of that games reviews and the spark to another internet fire.
It would seem IGN say the PS3 has the worse frame rate, while Gamespot say it has the best
IGN
These big open worlds, which are fully interactive, do come at a severe cost on PS3. There is considerable texture pop-in and noticeable framerate issues. Playing back-to-back with the 360 version, it's obvious that Ubisoft did not devote enough resources to the PS3 edition. The framerate is considerably worse, so much so that it begins to affect gameplay in the later levels. You can get through the first two-thirds of Assassin with the framerate being just an annoyance, but it becomes more of an issue for the final third of the missions.
Gamespot:
There are few differences between the Xbox 360 and PlayStation 3 versions. PS3 owners are blessed with a slightly more solid frame rate, although the 360 version features a little more contrast in the lighting, so it's pretty much a wash.

Opinion is fine for review score but for parts frame rate you have to state fact and it look like someone has screwed up.
