I went from basic TouchWiz (Samsung) to Nova, to Next 3d, to Go Launcher and now back to Nova.
Others I like include Themer and the Google Experience Launcher (GEL). GEL was giving me good voice response but my Note3 kept running out of battery so i killed it.
Re: Android Launchers - what different ones are you using?
^^If you dont know what launchers are..then this thread is not for you :D
Launcher is an app that lets you launch other apps and create shortcuts of apps. You can have all your shortcuts in one folder etc etc etc
