A332 vs A332RR

I’m just wondering is there any difference between A332 and A332RR. Seems RR stands for Rolls Royce engines. Is A332RR worth 20 GP for unlocking if I already unlocked A332?

My opinion is that they’re both not worth to unlock.


A332 is A332GE and A332RR

In the game A332GE is marked as just “A332” & A332RR is marked as “A332RR”. Anyway, are there any other differences except different look of engines below the wings? Smaller or bigger fuel consumption?
