I'm running FE10 myself, rooted blah blah thanks to sfhubs oneclick awesomeness! I just use the stock launcher. You can enable it by going into manage apps and selecting TWLauncher and clearing the defaults and then hit the home button and select Launcher instead. It's light and always responsive as can be. Touchwiz is pretty good, but once I started really using the stock launcher; I couldn't go back! lol
And just incase you were wondering; yes the odin one-clicks that sfhub provides are really that easy. Just read the directions and follow them to the "T" and you'll be fine. I went from the stock EL29 rom to EL29 rooted, to FD26 rooted, and now I'm sitting on FE10 rooted.
I wouldn't go back to GB for the world now. I am surprised at the results of FE10. However, I am a performance junkie and always try to run the minimum for the best performance. Heck, my PC even runs the minimum of applications as to not take any of the precious resources from my games. Some won't notice much of a difference, but I have. Can't wait to get the OTA so the devs can really start tweaking this kernel!
