On a different end of things, I'd like to compare the controls. Of course the Wii version boasted some awesome motion implementation, but alas it's a preference or choice to play as such. What I'd like to point out is the actual differences between the PS3 and 360 versions of the game.
The stick increments are completely different for both versions!
On the PlayStation 3, moving the character in a diagonal direction does not immediately activate unless the stick is almost at a 25 degree angle from the left or right position. The Xbox 360 however recognizes the diagonal position at a perfect 45 degree angle, it feels identical to the GameCube version.
Using the right analog stick to manipulate the camera via the PlayStation 3 version is roughly equal to or slightly less than the GameCube version. However the Xbox 360 version has multiplied this space by about two. The result of more viewable area may not seem meaningful, though it is crucial in regards to a usable 'pivot step.'
In Biohazard 5, the pivot step mechanism was key to fast paced set ups and aiming. It allowed users to manipulate the camera to their own advantage, lining up shots before they occur, along with taking corners and changing direction at a much faster pace. This was barely usable in Biohazard 4 due to the cameras properties, but in the Xbox 360 version it has for some reason seen a sizable buff.
Whether or not the properties were edited for the PS3 and 360 controllers alike (doubtful), or one versions controller benefited from the GameCube mechanical translation more (likely); the Xbox 360 version easily comes out on top in terms of in-game mechanics and controller translations.
On the preferential end of things, the 360 control layout is obviously more akin to the GameCube set up. The analog placement is the same and the structure is at least comparable, unlike PS3's swapped locations and different style of analog stick. This alone makes things feel more at home on the 360. 100% reflective and responsive directional control along with a buffed pivot step all make this version play wonderfully, while the PS3's smaller blemishes and awkward positioning leave the player wondering which method of control to use (d-pad or analog, flip a coin).
