If I hadn't already gotten used to SwiftKey (or, more correctly, if it hadn't already gotten used to me) I'd be using Swype. I do use it every now and again on my SGS3, but usually only when I'm typing in portrait mode. Both are great keyboards.
If you have problems installing, go to the Swype VIP section to download the installer again. You might have to register if you haven't already.
