I have the black strings on my home-built bass, but I found the additional tension on the E was causing problems with the tuner (they are the stock Ashbory tuners). So at present I have a hybrid set on there, with the E being the standard white fender string.
I actually like the sound of that white E better, and I like the sound of the black G better. Less phase-shifty sounding or something!
As far as stickiness goes, I use the talc pouch, and I am happy either with using it on either string. My main complaint about the black strings was that odd squeak you get when your finger rubs it along its axis. The talc mostly eliminates that, so again, I am happy the way things ended up.
