All of the above suggestions are good and all of those products will produce a slightly different sound. Basically what it comes down to is what type of sound do you want to hear, and how will they perform in your home with your system?
A simplification is:
Smooth = Gold plated.
More detailed with more bass slam = Rhodium plated.
And then there are the flavors in between.
My suggestions would be Furutech GTX-D Gold, Furutech GTX-D Rhodium, or Furutech NCF (R) Rhodium Plated.
Unfortunately, you won't know what you really like or the sound that will be produced until you audition any outlet and allow for break-in.
I'll bet you would be happy with whichever outlet you select as long as its a high-end outlet.
