I have used all three of the above cables; I would say that if the fibrax is the same as it was 6 years ago it is ace: I still have a set of fibrax outers that have lasted that long; 4 years on a mountain bike and 2 when i turned it into my commuter. Nice metal ferrules with rubber grommets inside and very tough.
Xtr is the nuts if you have lots of cable stops esp top tube cable routing and does come with enough ferrules fot this. My xtr cablles have been well filthy and are still shifting very nicely.
Goodridge is also very nice and has that blue plastic stuff for sealed cable runs but as mentioned, will only fit if you have down-tube cables (or only one mech as on my dh bike) -it is 2 ferrules short for top tube routing. Oh and you have to like blue as the plastic tube is very blue indeed. It is very tough though and you can buy more outer from crc for uninterrupted cable runs, or a couple of extra ferrules and gubbins for more cable stops.
