I thought i'd come back early.
Yes neither has made a huge leap infront of the other in terms of reliability but you also have to ask why did BA change back to RR when they ordered new 777's. There must have been a good reason why they would go through the expense of changing engine on the same type.
Must say though the GE90 is one quiet engine when it flies over my house.
