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
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
