I have a Shutter Precision, and a Shimano on two different bikes, and I can't tell any difference, they’re both great. With this “delux”, it makes less energy at slower speeds, which means for less resistance/notchiness, but higher speeds gets me full power. This wheel is going on my Rambouillet, so less resistance was key to me, but slower speed light flicker will be worse than the SP or Shimano, maybe.
