Launcher basic, what launcher to use and how

view story

http://forum.xda-developers.com – Hi, I am new to Android just recently switched from iOS. I thought about using a Launcher on my GS3 but I don't know which one to choose from as there are so many. Besides that, how do I disable touchwiz when I run launchers? Does disabling touchwiz disable the motion functions too? Please advise thanks! (HowTos)
