GO on my DX was easier to set up my gestures, and easier to get the scrollable dock bar. I initially had trouble finding gestures on GO, and didn't like my dock bar or scrolling effects as much as I did on Apex. I'm sold on Apex having run it for a couple of weeks. I wish Touchwiz allowed me to add extra screens, have a scrolling dockbar, and have a gesture that would reveal all the screens so I could quickly jump exactly where I wanted to be.
I wiped my DX two days ago before I gave it to another employee. Wow, did my DX screen look pitiful - now that I'm used to my S3.
Thanks for being willing to assist me with GO. I'm most likely to stick with Apex.
