Eugene (currently dev for 989) has a GB launcher 2 app that is awesome. Super simple, not really anything to customize but I love it. Basically an aosp gb launcher, no bells, no whistles, and certainly no problems.
I've used Go Launcher EX, ADW Launcher EX, Launcher Pro, TW Launcher, SweeterHome2, and SPB Shell 3D. SPB Shell is cool, but is really lacking in customization. I cant even change any of the icons and it can't even load contact pictures linked from facebook. ADW and Launcher Pro are alright, but I keep coming back to Go Launcher. I just stated playing around with SweeterHome2 (dead project that seems to have been revived very recently). It's still in beta and not on the market yet. It's got a lot of potential and the amount of customization is quite impressive, but the customization is not very intuitive or user friendly. For an example, check out some of dandylion's work here: http://dandylion7.deviantart.com/art/arrow-283946242 http://dandylion7.deviantart.com/art/For-284474547
