I have Launcher Pro, ADW paid version, GO Launcher, and Nova Prime. I'm currently using Nova right now, but my order for favorites other than Nova right now would be:
I haven't had Nova Prime long enough to decide whether I like it the most.
HTC Glacier/MyTouch 4G with TPU Fusion case.
White T-Mobile S3 with glacier Otterbox Commuter
-Frosty JB w/stock UVDLJC kernel if I remember correctly haha
