I'm so torn. I usually immediately put Nova Launcher on the phone to replace my previous S2,3,4 device TouchWiz Launchers. But this generation of TouchWiz just works so well and looks really good. The widgets are excellent and made compatible with other launchers (for the first time ever), the touch animations are nice and smooth, the transistions take the amount of time I expect, and the applications open quickly. I even love that they put the TouchWiz hotword in there so if you are on the main home screen with the Google Search widget it will launch Google Now for you. It is outstanding. The only improvement, and perhaps this is user error, but I don't know how to get the phone to wake to my voice anywhere but in Driving Mode.
