Without looking it up I would hazard a guess that there is some size difference between the Rolls Royce engines and the GE-90s. Probably not much but the RR engines always look slimmer but longer to me. That said, as Cadet57 put it they are as wide as a 737 so they are big ass no matter what.

I know the RR Trent 892 is only 110 inches in diameter as seen on the AA picture above, whereas the GE-90 is 135 inches. In fact the engine nacelle is, I believe, the same on GE90- 76, 94, and 115B. It is in fact the fan that is slightly larger. Because of the composite blades used in the 115b they are able to use a closer fit in the nacelle. The composites do not expand and contract near as much as titanium, or aluminum blades would. the P&W engine is 112 inches. There is therefore a fairly signifaicant difference in the ngines. In fact, I think the 777, 757 and the 747 have the most distinguishable engines differences.

There's a picture floating around of a BA 772A with the GE 90 parked next to a BA 737. It was arranged so that the engine was right in front of the 737. The nacelle is bascially the same size as the 737. Swanky...

Thanks for all the posts. I think its really interesting to try and identify each engine.
The GE90 is just huge, and has the titanium leading edge blades, and they are swept if its a 110/115B
The Rolls Royce is smaller (but still huge!), and has a kind of arched sweep to them.
And the Pratts... well the pratts are unremarkable.
