This is like asking what's the best rom.

Adw EX Launcher : you can argue with it it's just the fastest; it's SUPER snappy. Go Launcher is full of options but it get slower and slower. Like most of the Go Team products : starts great then it goes in all directions and becomes a factory...
Try scrolling the app drawer in vertical mode in Go Launcher then in ADW...and feel the pain for Go.
