Very good cables. I have them on two of my bikes, however, in my experience, if a good careful job is done of installation (correct length and routing the housings, cutting the ends of the housing cleanly and square, seating them properly in the ferules or stops, no kinks in the cables) any reasonable cables will work as well as high-end cables when new. High-end cables/housing will usually work well longer before performance degrades, and the Gore cables, with their sealing, will work well longer than others in wet nasty conditions.
