I've used a number of them. The Neovins sound very good, the True Coils are superlative. The True Coils really do sound like single coils, as that's mostly what they are. Even though they use a second coil for noise cancelling like most "noiseless" pickups do, it's a much smaller coil that doesn't do any picking up to speak of. So, all you really get is the tonal characteristics of a single coil. Downside is, they're not completely noiseless, but it knocks out about 90% of it, which is about 89% more than shielding regular single coils does. You almost don't notice it, but if you do you can easily eliminate what's left with a simple gate.
