Thought it would be, but best to check I'd stick with what you have as you know the cable is the right length and it will be less of a faff to fit. Only reason to change really would be if you have issues with the one you have.
Looking at your links, you have top swing now by the look of it?
I prefer top swing as it all looks more compact, but as Mike says there's fook all performance difference, my fav is xtr m950 with the differential cage it's no better for shifting but it doesn't rub as much when in extreme gears.
