Yeah, got Swiftkey today as a freebie from Amazon, and I find it comparable to the Gingerbread keyboard in size, layout, and recognition row. But Swiftkey's recognition/prediction seems noticeably better, and I like the recognition row more--it seems easier to select from there. I uninstalled Gingerbread.
My big hands have trouble with the little keys, even in landscape, but the recognition/prediction helps, and voice recognition works quite nicely so far in my limited testing. This would be my favorite of about six I've tried, if I had smaller fingers.
Minor point for most people: I love that you can dismiss Swiftkey with a downward swipe. No hard button press needed.
